HMGIY (High mobility group protein (non histone chromosomal) isoform I and Y)
IdentityOther names HMG-I(Y), HMGI/Y
Hugo HMGIY Location 6p21.3 centromeric to HLA-A, telomeric to D6S19
DNA/RNA
Description 10 144 bp; 8 exons, 7 introns Transcription HMGI and HMGY are encoded by the same gene and are generated trough
alternative splicing; exons 1-4 are not transcribed, exons 5-7 encode three DNA binding domains; exon 5 contains a 33 bp segment subject to alternative splicing; exon 8 encodes the acidic carboxy-terminal end; RNA length: 1.85 kb.
Protein
Atlas Genet Cytogenet Oncol Haematol 2001; 1 -5-
Description 107 amino acids; three DNA binding domains (AT hooks) Expression expressed in embryonal cells; expressed in a variety of normal human
adult tissues such as heart, brain, lung, skeletal muscle, kidney, pancreas, spleen, thymus, testis, ovary, small intestine, submandibular gland and leukocytes; expressed in transformed cells with a malignant phenotype and in human malignant tumors such as prostate, thyroid carcinoma and colorectal carcinomas and a subset of benign lipomas.
Localisation nuclear Function � architectural transcription, non histone, factor that binds to the minor
groove of AT-rich DNA; alters DNA conformation by introducing bends and supercoils; HMGIY was shown to be an essential component of enhanceosome (higher order transcription enhancer complex); positive induction of several genes including IFN-b, E-selectin, interleukin-2 receptor a-chain, the chemokine MGSA/GRO, and the class II major histocompatibility complex gene HLA-DRA; negative regulation by binding the promoter regions of interleukin-4 and GP91-PHOX. � the precise function remains to be elucidated; probable role in regulation of chromatin structure and gene expression, and transcriptional regulation; potential oncogenic role
Homology member of the HMGI protein family, structural (but not expression pattern) homology with HMGIC
MutationsSomatic HMGIY is found involved in chromosome rearrangements in benign
tumours, mainly mesenchymal tumors
Implicated inEntity Pulmonary chondroid hamartoma Disease benign tumor of the lung Prognosis good Cytogenetics the most frequent rearrangement is a reciprocal balanced translocation t(6;14)
(p21.3; q24); the rearrangement between chromosomes 6 and 14 can sometimes be complex, identifiable by FISH; molecular results also suggest that the translocations might be more complex than shown by conventional cytogenetics, with the presence of additional cryptic rearrangements; translocations involving partner chromosomes other than chromosome 14, such as chromosomes 1, 3, 4, 5, 10, 12, 17 have also been reported; inversions inv(6)(p21q21) or
Atlas Genet Cytogenet Oncol Haematol 2001; 1 -6-
inv(6)(p21.3q26) have been described Hybrid/Mutated Gene
in most cases, the breakpoint was extragenic, located within a 80 kb region 3' of HMGIY; aberrant transcripts with truncation of sequences from the 3' UTR have been described; in only one case with inversion inv(6)(p21q21), a hybrid intragenic fusion has been reported: HMGIY was fused to the LAMA4 (laminin a4 chain) gene
Abnormal Protein
the HMGIY-LAMA4 resulted from the fusion of the three HMGIY DNA-binding domains with the LAMA4 EGF-like domain
Oncogenesis the exact role of HMGI(Y)-LAMA4 fusion is not established yet Entity Lipomas Disease benign adipocyte tumors Prognosis good Cytogenetics a small subset (5-8%) of ordinary lipomas is characterized by 6p21
rearrangements, the most frequent of which being a reciprocal translocation t(3;6)(q28;p21); in contrast to other benign mesenchymal tumors with 6p21 rearrangement, there is no evidence of HMGIY rearrangements in ordinary lipomas yet; however, to be noticed, the breakpoint on 6p21 was shown to be located whithin a 80 kb region surrounding HMGIY in one lipoma case and HMGIY expression was correlated with 6p rearrangements in two ordinary lipomas and two spindle cell lipomas
Entity Uterine leiomyoma Disease benign mesenchymal tumors Prognosis good Cytogenetics approximately 40% of uterine leiomyomas present structural chromosomal
rearrangements, 5% of which involve 6p abnormalities; they include t(1;6)(q23;p21), t(6;14)(p21;q24) and t(6;10)(p21;q22) as well as inversions and translocations involving other chromosomal partners; the rearrangements are
Atlas Genet Cytogenet Oncol Haematol 2001; 1 -7-
sometimes complex, only identifiable by FISH analysis Hybrid/Mutated Gene
no hybrid gene has been described yet; as for other mesenchymal tumors, the breakpoint was extragenic, located within a 80 kb region 3' of HMGIY; one case of aberrant transcript with truncation of 1295 bp from the 3' UTR has been described
Abnormal Protein
HMGIY mRNA and protein levels do not always correlate, suggesting that post-transcriptional mechanisms are involved in the regulation of HMGIY
Entity Endometrial polyps Disease uterine benign tumors Prognosis good Cytogenetics several chromosomal abnormalities involving the 6p21.3 region, including
translocations, deletions, inversions have been described; various chromosomal partner regions, such as 14q24, 20q13, 2q35, 10q22, 8q12, 1p32, 7p15, 15q21, have been described to be associated with 6p21.3 in reciprocal translocations.
Hybrid/Mutated Gene
no hybrid gene has been described yet; as for other mesenchymal tumors, the breakpoint is extragenic, located within a 80 kb region 3' of HMGIY
Entity Hamartoma of the breast Disease benign tumor-like nodule of the breast, also called adenolipoma Prognosis good Cytogenetics one case with a t(1 ;6)(p21 ;21), involving the HMGIY gene has been described Entity Microfollicular adenoma of the thyroid Disease epithelial tumors Prognosis favorable Cytogenetics one case with a t(1;6)(p35;21) correlated with an overexpression of HMGIY has
been described

MLL is cleaved by taspase 1 into 2 proteins before entering the nucleus: a p300/320 N-term protein called MLL-N, and a p180 C-term protein, called MLL-C. The FYRN and a FRYC domains of native MLL associate MLL-N and MLL-C in a stable complex; they form a multiprotein complex with transcription factor TFIID.
Expression wide; especially in: brain, kidney, thyroid; expressed in Taned B lymphocytes and myeloid cells
Localisation nuclear, in punctate spots Function transcriptional regulatory factor; MLL may have yin-yang functions
though actions of MLL-N and MLL-C (e.g. desacetylation/acetylation); MLL-N acts as a transcriptional repressor; MLL can be associated with more than 30 proteins, including the core components of the SWI/SNF chromatin remodeling complex and the transcription complex TFIID. MLL binds promotors of HOX genes through acetylation and methylation of histones. MLL is a major regulator of hematopoesis and embryonic development, through regulation of HOX genes expression regulation ( HOXA9 in particular).
MutationsNote MLL is implicated in at least 10 % of acute leukaemias (AL) of various
types: acute lymphoblastic leukemias (ALL), acute non lymphocytic leukemias (ANLL), biphenotypic ALs, treatment related leukemias, infant leukemias; the prognosis is poor

IdentityOther names PTC, but this term was confusing with PTC/PKA
PTCH patched Hugo PTCH Location 9q22.3
(between FACC and XPAC PTCH1 is flanked by the microsatellite markers D9S196 and D9S287; a microsatellite marker, 1AJL, is located inside the gene
DNA/RNADescription 24 exons, exon 24 is non-coding; 34 kb Transcription alternate splicing: 3 different 5' termini; 6.5 kb mRNA; coding
sequence: CDS 1 ... 4344
Protein Description glycoprotein; 12 transmembrane domains, 2 extra cellular loops,
intracellular N-term and C-term and sterol-sensing domain (SSD) Expression widely expressed at low levels; increased levels in cells receiving a
hedgehog signal Localisation transmembrane protein, cellular membrane, intracellular vesicles Function part of a signalling pathway; opposed by the gene products of hedgehog
genes; transmembrane protein; is thought to have a repressive activity on cell proliferation; the recent demonstration of NBCCS syndrome (see below) as a chromosome instability syndrome suggests that this protein has a role in DNA maintenance, repair and/or replication
MutationsGerminal germ-line mutations lead to protein truncation in naevoid basal cell
carcinoma syndrome (NBCCS) patients (see below); mutations types are variable : nucleotide substitutions (missense/nonsense), small deletions, or small insertions mainly, leading to protein truncation; these mutations have been observed in most exons; there is, so far, no hot-spot.
Somatic mutation and allele loss events in basal cell carcinoma, in NBCCS and in sporadic basal cell carcinoma are, so far, in accordance with the two-hit model for neoplasia, as is found in retinoblastoma; mutation and allele loss have also been found in sporadic primitive neuroectodermal tumours (PNETs), sporadic medulloblastomas and in a few cases of esophageal squamous cell carcinoma and invasive transitional cell carcinoma of the bladder; mutations have also been reported in a low frequency of sporadic trichoepitheliomas and in sporadic odontogenic keratocysts

RON protein tyrosine kinase (RON); Macrophage stimulating protein receptor (MSP-receptor) Hugo MST1R Location 3p21.31 between LIMD1 and CCXCR1; between D3S1568 and D3S3822
DNA/RNA
Description Twenty coding exons. All exons are small in size, ranging from 93 bp to 253 bp, with
the exception of exon 1 (>1 kb). Exon 1, 2 and 3 code for the SEMA domain of the RON protein (red). Exons 4 codes for a PSI domain (orange), a modular structure about 50 amino acid long containing eight conserved Cys residues, putatively involved in protein-protein interactions. The sequence between exon 4 and 12 codes for four repeated modular structures called IPT (yellow); these domains are found in cell surface receptors such as MET and RON as well as in intracellular transcription factors where they are involved in DNA binding. Part of exon 12 codes for the transmembrane domain, (pink). Exons 14 to 20 codes for the kinase domain (blue).Four-digit numbers refer to splice sites location, based on RON cDNA sequence
Transcription Two major transcripts are detected, respectively 4.5 kb and 2 kb. ORF: 4204 bp
Protein
Atlas Genet Cytogenet Oncol Haematol 2001; 1 -64-
Description The RON protein is a glycosilated heterodimeric protein composed of
one a- (35 kD) and one b-chain (150 kD) linked by an unknown number of disulfide bonds. The two chains derive from a single-chain precursor of about 185 kD that undergoes proteolytic cleavage at the basic amino acid site KRRRR. The a-chain is extracellular. The b-chain has an extracellular part, a one-pass transmembrane helix and an intracellular part containing the tyrosine kinase domain. The first 24 amino acids made the putative signal peptide (green). The SEMA domain (consisting of most of a- and part of b- chain) contains the ligand (MSP) binding pocket (unpublished data). Tyrosine residues 1238 and 1239 (upward arrowheads in the figure) are essential for up-regulation of RON catalytic activity. Tyrosine residues1353 and 1360 (downward arrowheads, in the figure) make a docking site that mediates high affinity interactions with multiple SH2-containing signal transducers
Expression RON is expressed in human keratinocytes (it was initially cloned from a keratinocytes cDNA library). By Northern blot was found expressed in the following normal human tissues: skin, lung, bone marrow, small intestin, heart, pancreas, thyroid, prostate, testis (unpublished data), colonic mucosa and in a variety of cell types: granulocytes and monocytes, hematopoietic cells such as erythroid and myeloid progenitor cells, macrophages, osteoclasts, bone marrow megakaryocytes, epithelial and neuroendocrine cells
Localisation Transmembrane protein. Function The ligand for RON is MSP. Originally, MSP was described as a serum
factor enhancing the chemotactic response of murine peritoneal macrophage to the C5a fraction of complement, but RON/MSP complex has a much broader spectrum of activity. Ligand-stimulated RON activates the pathways regulating cell adhesion and motility, growth and survival. STK (the mouse ortholog) is essential for peri-implantation development during gestation, as STK-deficient mice (STK-/-) are viable only through the blastocyst stage. Hemizygous mice (STK+/-) grow to adulthood; however, they are highly susceptible to endotoxic shock and appear to be compromised in their ability to down-regulate nitric oxide production. These results suggest STK has a limiting role not only in the inflammatory response but also in early mouse development
Homology RON belongs to the MET receptor tyrosine kinase (RTK) family. On the basis of the presence of multiple PSI domains and a SEMA domain, it has been proposed that plexins, MET RTK family and VESPR (virus-encoded semaphorin receptor) are classified as semaphorins. RON orthologs have been identified in mouse (STK), chicken (c-sea) and

Xenopus
MutationsGerminal Several Single Nucleotide Polymorphisms (SNPs) were found in healthy
CEPH individuals: A993G :Gln322Arg (index of heterozygosity: 0.28); C4024T (same-sense variant, index of heterozygosity: 0.03); A4031G: Arg1344Gly (index of heterozygosity: 0.46)
Somatic T915C: Leu296Pro was found in the tumor DNA of one single patient affected with adenocarcinoma of the lung. The mutated protein is not constitutively activated. The mutation has no causative role in the disease. Experimental introduction in the RON kinase domain of amino acid substitutions D1232V and M1254T - initially found in the oncogenes KIT, RET and MET, involved respectively in mastocytosis, Multiple Endocrine Neoplasia type 2B and renal papillary carcinoma - results in activation of oncogenic capacity and triggers a strong metastatic activity of RON. Expression of these RON mutants causes cellular accumulation of b-catenin via inhibition of its association with the axin/GSK complex and subsequent protection from proteasomal degradation (Danilkovitch-Miagkova, personal communication).
Implicated inEntity RON was found over-expressed in infiltrating breast carcinomas. A
constitutively activated splicing variant of RON (lacking exon 11) was found in the gastric carcinoma cell line KATO-III. This variant induces activation of cell dissociation, motility and invasion of extracellular matrices. The same variant was found in malignant colonic mucosa. Another splicing variant, lacking exons 5 and 6, was found in the human colon carcinoma cell line HT-29.Truncated STK - the mouse RON ortholog - confers susceptibility to Friend virus-induced erythroleukemia in mice, and c-sea, the avian ortholog, causes erythroblastosis in chickens.

Clinics and PathologyDisease Myeloid lineage (MDS, ANLL, therapy related ANLL, CML, MPD);
features similar to those of the 3q21q26 syndrome including normal or elevated platelet count at diagnosis, megakaryocytic hyperplasia and dysplasia. Very rarely in lymphoid lineage
Phenotype / cell stem origin
of 39 cases, there were: 22 myelodysplastic syndromes (MDS) (17/22 transformed into refractory acute non lymphoblastic leukemia (ANLL) of -M1 or -M4 type), 8 de novo ANLL, 3 therapy-related MDS, 2 polycythemia vera, 1 essential thrombocythemia, 1 chronic myelogenous leukemia (CML), 1 multiple myeloma, 1 waldenstrom's macroglobulinemia
Epidemiology patients are aged: 30-80 yrs Clinics Roughly 50% of patients present with MDS, another 10% with therapy
associated MDS, 25% with de novo AML, and the remainder with a range of other myeloproliferative disorders. The majority of MDS patients transform into AML with a short preleukemic phase. Blood data: frequent thrombocytosis or normal platelet count
Atlas Genet Cytogenet Oncol Haematol 2001; 1 -80-
Cytology frequently characterized by dysmegakaryocytopoiesis Pathology The pathology is typical of MDS, often with a prominent monocytic
component. Trilineage dysplasia. Acute leukemias that evolve usually show the morphology of M4 AML.
Treatment Patients are treated with conventional chemotherapy for AML. Prognosis Very poor so far: from 16 cases, median survival was 6 mths in ANLL,
20 mths in MDS
CytogeneticsNote Other rearrangements showing similar clinical features include
inv(3)(q21q26), t(3;3)(q21;q26), t(3;5)(q21;q31), t(3;8)(q21;q24), and t(3;21)(q26;q22). The breakpoints in 3q21 cluster in a 50 kb region centromeric to the breakpoint in inv(3)(q21;q26) and the ribophorin gene (RPN1). The breakpoints at 1p36 are clustered in a 90 kb region at 1p36.3.
Additional anomalies del (5q) in 5 of 20 cases (1/4)
Genes involved and ProteinsNote Mechanisms of Oncogenesis : The available data suggest that
transcription of MEL1 (MDS1/EVI1 -like gene) is activated as a result of translocation bringing the gene just 3Õ to RPN1 gene at 3q21. MEL1 is a 1257 amino acid protein that is homologous (63% similar in amino acid sequence) to EVI. The mechanism of activation of MEL1 is similar to EVI1 that is activated by juxtaposition 3Õ to RPN1 in the t(3;3)(q21;q26) and 5Õ to RPN1 in the inv(3)(q2126). It appears that MEL1 is normally expressed in uterus and kidney and not in normal hematopoietic cells or in leukemias that lack the t(1;3)(p36;q31 The MEL1 protein contains 2 DNA binding domains (7 C2H2 zinc finger repeats at the amino terminus and 3 zinc finger repeats at the carboxyl terminus). The amino terminal domain of MEL1 contains a PRD domain, a motif also found in the same location in the MDS1/EV1 protein but not in MDS1). This is of interest because this domain is also found in RIZ, PRDI-BF1, and egl-43 and is homologous to the SET (Suvar3-9, Enhancer of zeste, Trithorax) domain that present in MLL. Inclusion of this domain in EVI1 appears to convert EVI1 from a transcriptional repressor to an activator. Therefore MEL1 may be a transcriptional activator. The target genes of MEL1 have not been identified.

there is variation in the reported incidence due to heterogeneity of histologic classification and to the different sensitivity of the detection methods � 10 to 15% of follicle centre cell lymphoma (FCCL) and mantle cell lymphomas (MCL) may carry a 17p- chromosome; minority of marginal zone B-cell lymphomas may be associated with 17p deletion � this anomaly is rarely found in T-cell NHL
Prognosis the 17p- chromosome was reported to predict for a poor prognosis in low grade lymphomas; any abnormality of chromosome 17 was also reported to negatively affect survival in lymphomas of all histologic grades
CytogeneticsCytogenetics Morphological
� the deleted segment may vary in size and many cases with sub-microscopic deletions involving the 17p13 band were reported by FISH; cases with unbalanced 17p translocations leading to 17p loss were also described; these cases may be associated with dicentric rearrangements � the 17p- is usually associated with transformation of a low-grade FCCL with t(14;18) into a high grade lymphoma; likewise, there is a higher incidence of 17p- in the blastoid variant of MCL with t(11,14) than in the typical form the deletion may be detected by G or R-banding; FISH using a 17p13/p53 probe is recommended, this technique being more sensitive than conventional cytogenetics
Cytogenetics Molecular
Genes involved and ProteinsNote the majority of cases with 17p- carry a p53 gene deletion, associated
with mutation of the remaining allele; there may be a small fraction of cases with a more distal deletion involving an as yet unidentified locus

Clinics and Pathology
a very large spectrum of hematological malignancies as myelodysplastic syndromes (MDS), acute non lymphocytic leukemias (ANLL), polycythemia vera, chronic neutrophilic leukemia as described in various types of hematological disorders, 20q- appears as a primary karyotypic abnormality occurring in a pluripotential hematopoietic stem cell; the pathogenic mechanism by which 20q- alters the hematopoietic stem cells in hematological disorders remains unknown; 20q- may confer a proliferative advantage to myeloid cells through deletion of a tumor suppressor gene
an interstitial or terminal deletion of the long arm of chromosome 20 (20q-) has been described as the second most frequent sole clonal structural abnormality (5 %) behind t(9.22)
Disease
Phenotype / cell stem origin
Epidemiology
� in MDS, 20q- alone is associated with a good prognosis regarding survival and potential for AML evolution, as defined by the International Prognostic Scoring System (IPSS) for MDS prognosis
Prognosis
� in de novo acute leukemia, a poor response to treatment and a reduced survival is observed � in myeloproliferative disorders, the presence of 20q does not appear to adversely affect survival
CytogeneticsCytogenetics the breakpoint on chromosome 20 is not constant; 20q- is frequently
Atlas Genet Cytogenet Oncol Haematol 2001; 1 -87-
Morphological associated with other cytogenetic abnormalities as del(5q), trisomy 8, trisomy 21, deletions or translocations involving the long arm of chromosome 13; a newly described translocation t(11;20)(p15;q11) resulting in a NUP98- TOP1 fusion gene was described in therapy-related myelodysplastic syndrome (RAEB); t(11;20)(p15;q11) is a rare recurrent translocation reported in patients with MDS, ANLL and polycythemia vera
Cytogenetics Molecular Additional anomalies
a small fragment (around 8 Mb), proximally flanked by D20S206 and distally by D20S119 and UT 654 was identified using FISH del(5q), trisomy 8, deletions or translocations involving 13q and trisomy 21
Genes involved and ProteinsNote genes remaining within this deleted region are topoisomerase 1 (TPO1-
OMIN 126420), phospholipase C (PLC1), hepatocyte factor nuclear 4 (HNF4) and adenosine desaminase (ADA); recently, a new gene KRML transcriptional regulator was mapped in the smallest commonly deleted region in malignant myeloid leukemias

Juvenile Chronic Myelogenous Leukemia (JCML)
IdentityNote the proper terminology of this disorder is controversial; many authors,
including the European Working Group on MDS in Childhood favor the term JMML; another working group suggests using the term JMML syndrome with a qualifier with or without monosomy 7 or 7q-
Clinics and PathologyDisease JCML is a chronic myeloproliferative disorder that typically affects
young children: more than 95% of cases are diagnosed before age 4 Phenotype / cell stem origin
evidence exists for leukemic involvement of CD34-positive stem cells and monocyte-macrophage, erythroid, and B-lymphoid lineages in cases with cytogenetic abnormalities
Epidemiology annual incidence is estimated to be roughly 4/million; median age 1-4 yrs; sex ratio: 1.4M/1F
Clinics
� proposed clinical criteria from the International Juvenile Myelomonocytic Leukemia Working Group includes: 1. white blood cell count > 13 x 109/L (corrected for nucleated red blood cells) 2. absolute monocyte count > 1 x 109/L (corrected) 3. presence of immature myeloid precursors (myelocytes, promyelocytes, and myeloblasts) in the peripheral blood 4. bone marrow aspirate revealing < 30% blasts 5. no Ph chromosome on cytogenetic assessment
� splenomegaly, lymphadenopathy, and skin rash are common; typical peripheral blood findings include leukocytosis (usually less than 100 x 109/L), monocytosis, and thrombocytosis with variable degree of left shift; myeloblasts average about 5% of total nucleated cells; elevation of fetal hemoglobin (hbF) very common; absence of the Philadelphia chromosome in all cases
� about 15% of cases are associated with neurofibromatosis type 1 ( NF-1 mutation)
Pathology � blood: leukocytosis, monocytosis, left shift in myeloid maturation, circulating mucleated red blood cells � bone marrow: hypercellular marrow with mildly increased M:E ratio (typically 5:1), dispersed erythroid elements, and decreased numbers of megakaryocytes; dyplasia is usually not prominent
Atlas Genet Cytogenet Oncol Haematol 2001; 1 -90-
Treatment intensive chemotherapy and all trans retinoic have not been shown to induce durable remissions; complete remissions have been achieved with stem cell transplantation
Prognosis the disease is uniformly fatal when treated with conventional chemotherapy; among those who undergo bone marrow transplantations, the majority ultimately relapse, with an overall survival rate of 25%
CytogeneticsCytogenetics Morphological
other than the frequent association with monosomy 7, no consistent cytogenetic abnormalities have been identified; whether the infantile monosomy 7 syndrome is distinct from JCML is controversial
Genes involved and ProteinsNote mechanisms of Oncogenesis:
JCML patients show spontaneous growth of granulocyte-macrophage colony forming units (CFU-GM) from peripheral blood, which appears to be the result of hypersensitivity to GM-CSF, IL-3, or SCF; cases associated with NF-1 are likely to be the result of constitutive activation of the Ras pathway as a result of decreased GT Pase activity although there is also evidence of a GAP independent function; up to 30% of cases show mutations in K-ras and N-ras; the importance of the RAS pathway has been confirmed in mouse models with targeted disrupted of Nf-1; recently data suggest that TNFa produced by neoplastic cells may prevent expansion of hematopoietic progenitors

11q23 rearrangements in leukaemia (updated: old version not available)
Clinics and PathologyDisease de novo and therapy related leukaemias; acute non lymphocytic
leukaemia (ANLL) and acute lymphocytic leukaemia (ALL) grossly represent half cases each; myelodysplasia (MDS) in the remaining 5%; biphenotypic leukaemia at times (likely to be more frequent with more investigations); 11q23 rearrangements in treatment related leukaemias (5-10% of 11q23 cases) are found mainly following a treatment with anti-topoisomerase II, or an intercalating topoisomerase II inhibitor, but also after alkylating agents treatment and/or radiotherapy; the prior cancer is variable.
Epidemiology
Phenotype / cell stem origin
ANLL: M5a in half cases, M4 (20%), M1 or M5b (10% each), M2 (5%); ALL: B-cell mostly, L1 or L2, CD19+ in 60% of B-ALL cases, CD10+ 35%; T-ALL in rare cases (<1%); MDS: most often RA or RAEB1T. 25% are infant (<1 yr) cases; children and adults each represent 50% of cases; M/F = 0.9 (NS) See also 11q23 rearrangements in childhood acute lymphoblastic leukemia: Clinical aspects and congenital leukemias
Clinics organomegaly; frequent CNS involvement (5%); high WBC (> 50 X 109/l in 40%).
Molecular studies have identified a human homologue of the drosophila trithorax gene (designed HRX or MLL). MLL is a developmental regulator and is structurally altered in leukemia associated translocations that show an abnormality at band 11q23. The MLL gene on 11q23 is involved in a number of translocations with different partner chromosomes. The most common translocations observed in childhood AML are the t(9;11)(p21;q23) and the t(11;19)(q23;p13.1); other translocations of 11q23 involve at least 30 different partners chromosomes. Molecular studies have shown that MLL is rearranged more frequently than is revealed by conventional cytogenetic studies. A partial tandem duplication of MLL gene has also been reported in the majority of adult patients whose leukemic blast cells have a +11 and in some with normal karyotype. There is a strong association between AML M5/M4 and deletion and translocations involving 11q23. Sometimes cases of 11q23 M5B and M4, and occasionally M2 or M1 also show MLL rearrangement. Two clinical subgroups of patients have a high frequency of 11q23 aberration and M5 subtypes: one is AML in infants with MLL rearrangement in about 50% of cases; the other group is "secondary leukemia" (sAML) potentially after treatment with DNA topoisomerase II inhibitors. In general the translocations in these leukemia are the same as those occurring in "de novo" leukemia i.e. t(9;11), t(11;19) - Courtesy Georges Flandrin, CD-ROM AML/MDS G. Flandrin/ICG. TRIBVN
Prognosis very poor in general; variable according to the translocation, the phenotype, the age , and whether the leukaemia is de novo or treatment related.

Clinics and PathologyDisease the overall incidence in NHL is 4-5%, the highest incidence having been
reported in mantle cell lymphoma, where up to 70% of the cases studied by FISH may harbour a cryptic deletion in association with the classical t(11;14) translocation; FISH detects an approximate 10% incidence of 11q deletion among other histologic subsets of B-NHL; among diffuse large B-cell lymphoma the 11q- chromosome shows a preferential association with the immunoblastic variant; sensitive molecular cytogenetic methods may show 50-70% of T-cell prolymphocytic leukemia to carry an 11q deletion involving the ATM gene
Prognosis a possible association between 11q-/ATM- and poor prognosis in B-cell NHL was reported
CytogeneticsCytogenetics Morphological
the chromosome 11q deletion occurring in NHL most frequently affects the q22-23 bands; the 11q- anomaly occurs as a secondary change in the majority of cases
Cytogenetics Molecular
because the size of the deleted segment may be beyond the resolution power of conventional banding analysis, many cases can only be detected by interphase FISH or other genetic methods using probes targeting the 11q22.3-q23.1 region
Genes involved and ProteinsNote the region of minimal deletion was narrowed down to a 2-3 Mb pair
segment where the ataxia teleangiectasia ( ATM) gene is located;
sequencing studies showed mutation in the remaining ATM allele in a significant fraction of cases

del(7q) in non-Hodgkin's lymphoma (NHL)
Clinics and PathologyDisease the frequency of 7q deletions in unseletced NHL is less than 5%; an
association with splenic marginal zone B-cell lymphomas (MZBCL) was established, with a 20-30% incidence; sensitive molecular genetic studies found a 40% incidence in splenic MZBCL, as against a 7% incidence in other forms of NHL
Prognosis there may be an association of 7q- with tumor progression or transformation into a high-grade MZBCL
CytogeneticsCytogenetics Morphological
7q deletions or unbalanced 7q translocations in NHL usually involve a relatively large segment, usually centered around the 7q22-q32 region
Cytogenetics Molecular
conventional G- or R-banded preparations detect the majority of cases; however some patients with submicroscopic deletion were detected by FISH or loss-of-heterozigosity studies
Genes involved and ProteinsNote the involved gene(s) are unknown; the minimal region of deletion in
MZBCL carrying a 7q- chromosome was narrowed down to a 5cM segment defined by the D7S685 and D7S514 markers; homozygous deletion of the D7S685 was reported, suggesting that a tumor suppressor gene relevant to lymphomagenesis may be located in this region; a recurrent 7q21 translocation involving a small 3.6 Kb segment upstream of the cyclin-dependent kinase 6 gene ( CDK6), with resultant CDK6 overexpression, was described

t(1;14)(p22;q32) in non Hodgkin's lymphoma (NHL)
Clinics and PathologyDisease the translocation is cytogenetically detectable in a minority of extranodal
MALT lymphomas; irrespective of the presence of the 1;14 translocation, mutation or deletion of the BCL10 gene located at 1p22 can be detected by molecular genetic methods in 5-10% of extra-nodal MALT lymphomas, follicle centre cell lymphoma and diffuse large B-cell lymphoma; among MALT lymphoma a preferential association was noted with high-grade histology
Prognosis in MALT lymphoma there may be an association with aggressive histology and antibiotic-unresponsive forms

+3 or trisomy 3 in non Hodgkin's lymphoma (NHL)
Clinics and PathologyDisease trisomy 3 occurs more frequently in T-cell lymphomas than in B-cell
lymphomas � globally, 20-30% of T-NHL may carry trisomy 3, the highest incidence having been noted in lymphoepithelioid lymphoma, in low-grade peripheral T-cell lymphoma, in angioimmonoblastic lymphadenopathy and in adult T-cell leukemia-lymphoma � trisomy 3 is relatively rare in B-NHL, with the exception of marginal zone lymphomas (MZL) and mantle cell lymphoma (MCL); in MZL, total or partial trisomy 3 may occur in 50-70% of cytogenetically abnormal cases, with a reported incidence by interphase FISH in the 50-85% range; the incidence does not appear to vary according to the clinicopathologic features, with similar frequency in the extra-nodal MALT lymphoma, in the nodal and the splenic form of MZL; trisomy 3/3q was reported in 10-15% of MCL with an higher incidence (up to 40%) by molecular cytogenetic techniques; sporadically, other low-grade and high grade B-lymphoid tumors may carry trisomy 3/3q
Prognosis the prognostic significance of trisomy 3 in T-cell and B-cell lymphomas is unknown; there does not appear to be a role for trisomy 3 in tumor progression from low-grade MALT lymphoma to the high grade form, whereas gains of 3q may be associated with the aggressive blastoid variant of MCL
CytogeneticsCytogenetics Morphological
trisomy 3 may be total or partial; commonly overrepresented segments in partial trisomy 3 include the q21-23 region and the q25-29 region; total/partial trisomy 3 may occur as an isolated anomaly in a minority of cases
Cytogenetics Molecular
the anomaly is readily detectable by G- and R-banding in most cases; however, FISH using a centromeric probe is more sensitive than conventional cytogenetics, allowing for the study of non-dividing cells and for the detection of partial trisomy in complex karyotypes with marker chromosomes

-Y
Y loss in leukemia
IdentityLoss of the Y chromosome from individual metaphases is common in metaphase cells from both PHA-stimulated lymphocytes and spontaneously dividing bone marrow cells. The frequency of Y loss is greater in older men, and the size of the 45,X,-Y cell population probably increases gradually with advancing age. (In females, a corollary loss of one X chromosome also occurs with advancing age.) This natural phenomenon challenges our ability to distinguish between a normal and a disease-associated 45,X,-Y clone.
Note
Clinics and PathologyDisease -Y is frenquently observed in myeloproliferative diseases (MPD),
myelodysplasic syndromes (MDS), acute non lymphocytic leukemias (ANLL), and can also be seen in lymphoproliferations
Epidemiology In CML with t(9;22) and in ANLL with a t(8;21), loss of the Y chromosome tends to occurs at a younger age than in the general population
Clinics � Partial or complete reappearance of the Y chromosome has been described in several cases of ANLL in remission. In most or all of these ANLL cases, the 45,X,-Y cell population represented 80-100% of pre-remission metaphases. These observations support the interpretation that the leukemia cell karyotype is 45,X,-Y. � In MDS, the proportion of -Y cells has been observed to increase, decrease, remain stable, or fluctuate up and down on follow-up studies. � In four cases of Hodgkin disease, simultaneous fluorescence immunophenotyping and FISH showed that the -Y cell population was probably independent of the Hodgkin disease in at least two of the patients. It is notable that the -Y cells represented fewer than 10-15% of the metaphase cells in all four cases.
Cytology no known association Prognosis In ANLL, a 45,X,-Y karyotype is believed to have an intermediate
prognosis. In MDS, the prognosis appears to be neutral or favorable. There are insufficient data for MPD or lymphoproliferative disease
� In PHA-stimulated lymphocyte karyotype studies of males, about 2% have one or more cells with loss of the Y chromosome. Cells with -Y are observed more often in males over age 55 than in younger males. In all age groups, the proportion of -Y cells is usually under 10%. � The pattern of Y loss is more striking in bone marrow aspirate karyotype studies. Here, clonal Y chromosome loss as a sole abnormality in the karyotype is a common finding. A 45,X,-Y karyotype is observed in about 6% of bone marrow karyotype studies from males, and it represents 15-20% of abnormal karyotypes. � The frequency of -Y cells increases with advancing age and is significantly greater in cases with MDS, MPD, ANLL, or lymphoproliferative disease than in subjects who have no evidence of disease. Subjects with no evidence of disease rarely exhibit more than 75% of cells with 45,X,-Y. Thus, if fewer than 75% of metaphase cells are -Y, the disease association is uncertain. However, if 75-100% of metaphase cells are -Y, the karyotype probably is disease-associated, even in older men. � Chromosome rearrangements involving the Y chromosome are rare in cancer and leukemia. Loss of the Y chromosome, in contrast, is a common secondary change in cancer cells and in a few leukemias (see below).
Probes all available probe for the Y chromosome Additional anomalies
In association with t(9;22) in CML and with t(8;21) in FAB-M2 ANLL, loss of the Y chromosome is generally considered a secondary event of no added clinical significance.
Genes involved and ProteinsNote genes involved, if any, are unknown
To be noted It is not known whether the Y chromosome loss is the critical mutational
event. Likewise, it is not known whether the Y chromosome loss is a secondary genetic change, or if the critical (submicroscopic) genetic change simply occurs by chance in a -Y cell. Speculatively, loss of the Y could provide a proliferative advantage simply because it tends to replicate late in S-phase. Its loss might therefore shorten the cell cycle slightly.

Nervous system: Astrocytic tumors
ClassificationNote Astrocytic tumors comprise a wide range of neoplasms that differ in their
location within the central nervous system (CNS), age and gender distribution, growth potential, extent of invasiveness, morphological features, tendency for progression and clinical course; there is increasing evidence that these differences reflect the type and sequence of genetic alterations acquired during the process of transformation.
The following clinicopathological entities can be distinguished :
Clinics and PathologyEtiology � gliomas have been observed following therapeutic irradiation.
� familial clustering of gliomas is not uncommon: the association with defined inherited tumor syndrome incuding the Li-Fraumeni syndrome, Turcot syndrome, and the NF1 syndrome
3. Anaplastic Astrocytomas / Grade III: anaplastic astrocytomas occur in the same locations as astroc
Epidemiology diffuse astrocytomas are the most frequent intracranial neoplasm and account for more than 60% of all primary brain tumors; the incidence differs between regions, but there are 5 to 7 new cases per 100.000 population per year
Clinics 1. Pilocytic Astrocytomas / Grade I: pilocytic astrocytomas arise throughout the neuraxis and are common in children and in young adults; pilocytic tumors of the optic nerve cause loss of vision; pilocytic astrocytoma of the hypothalamus and third ventricular region primarily affect children; but tumors of the cerebral hemispheres generally occur in patients older than those with visual system or hypothalamic involvment
2. Fibrillary Astrocytomas / Grade II: fibrillary astrocytomas arise in the cerebral hemisphere of young to middle-aged adults and the brain stem of children; occasional examples occur in the cerebellum or spinal cord; at any site these astrocytomas must be distinguished from pilocytic astrocytomas; all such tumors are pilocytic astrocytomas in the optic nerve whereas most are of the fibrillary type in the brain stem
glioblastoma, but the majority affect the cerebral hemispheres; anaplastic astrocytomas generally occur in patients a decade older than those with better differenciated astrocytomas and a decade younger than those with glioblastomas
another subgroup of glioblastoma can be distinguished: the giant cell glioblastomas; histologically it is a glioblastoma with giant cells (500 mm in diameter): it develops clinically "de novo "; it is associated with a favorable prognosis
4. Glioblastoma Multiforme / Grade IV: glioblastoma is by far the most common glioma; it affects principally the cerebral hemispheries in adults and the brain stem in children; but they are most frequent after the fifth decade; most glioblastomas are solitary but occasional examples are geographically separate in the same patient and warrant the designation " multicentric "; usually, it appears as a central area of hypodensity surrounded by a ring of contrast enhanced and penumbra of cerebral oedema glioblastoma multiforme may develop de novo (primary glioblastoma) or though progression from low-grade or anaplastic astrocytoma (secondary glioblastoma); patients with a primary glioblastoma are usually older, present a rapid tumor progression and a poor prognosis; patient with secondary glioblastomas are younger and tumor progress more slowly, with a better prognosis; these two groups are histologically indistinguishable
Pathology 1. Pilocytic Astrocytomas / Grade I: this predominantly peadiatric brain tumor is a circumscribed astrocytoma composed in varying proportions of compacted and loose textured astrocytes associated with rosenthal fibers, eosinophilic granular bodies, or both; the lesion described is sometimes referred to as the " juvenile pilocytic astrocytoma "
2. Fibrillary Astrocytomas / Grade II: this tumor is a well differanciated diffusely infiltrating neoplasm of fibrillary astrocytes
3. Anaplastic Astrocytomas / Grade III: this tumor is an astrocytic tumor of fibrillary type which is intermediate in differenciation between the better differenciated astrocytoma and glioblastoma; it is an astrocytic neoplasm that typically exceeds well differenciated astrocytoma in terms of cellularity, nuclear pleomorphism and hyperchromasia necrosis of glioblastoma
4. Glioblastoma Multiforme / Grade IV: this tumor is a highly malignant glioma most closely related to fibrillary or diffuse astrocytic neoplasms; glioblastomas are cellular masses with varied tissue patterns; it appears either infiltrating or discrete, with typical or atypical mitoses, endothelial vascular proliferation and necrosis
Treatment treatment differs according to grade and location of tumor pilocytic astrocytomas can be cured by complete resection of tumor; if exeresis is not possible due to the location of the tumor, chemotherapy is indicated in young children and radiotherapy in adults in fibrillary astrocytomas, the treatment consists of total and extent resection of tumor in anaplastic tumors and glioblastoma multiforme, the treatment consists of total resection and radiotherapy and chemotherapy after surgery in low grade astrocytomas, a correlation of proliferation was reported (Ki67 index) with clinical outcome; the proliferative potential correlates inversely with survival and time to recurrence; the mean survival time after surgery is 6-8 years in low-grade astrocytomas; after surgery, the prognosis depends on whether the neoplasm undergoes progression to a more malignant phenotype; in pilocytic astrocytomas, total cure is possible after total resection; in fibrillary astrocytomas reccurrence is frequent . in anaplastic astrocytomas and in glioblastomas, evaluation of the extent of resection can be a prognostic factor; prognosis is generally poor (about one year); patients below 45 yrs have a considerably better prognosis than elderly patients; primary glioblastomas have a short clinical history with a poor prognosis; survival is better in secondary glioblastomas
Prognosis
CytogeneticsCytogenetics Morphological
� In astrocytomas grade I, normal karyotype is observed most frequently; among the cases with abnormal karyotypes, the most frequent chromosomal abnormalityis loss of the X and Y sex- chromosomes; loss of 22q is found in 20-30% of astrocytomas; other abnormalities observed in low grade tumors include gains on chromosome 8q, 10p, and 12p, and losses on chromosomes 1p, 4q, 9p, 11p 16p, 18 and 19 � In anaplastic astrocytomas, chromosome gains or losses are frequent: trisomy 7 (the most frequent), loss of chromosome 10, loss of chromosome 22, loss of 9p, 13q; other abnormalities, less frequently described are: gains of chromosomes 1q, 11q, 19, 20, and Xq � Glioblastomas show several chromosomal changes: by frequency order, gain of chromosome 7 (50-80% of glioblastomas), double minute chromosomes, total or partial monosomy for chromosome 10 (70% of tumors) associated with the later step in the progression of glioblastomas partial deletion of 9p is frequent (64% of tumors): 9pter-23; partial loss of 22q in 22q13 is frequently reported loss or deletion of chromosome 13, 13q14-q31 is found in some glioblastomas trisomy 19 was reported in glioblastomas by cytogenetic and comparative genomic hybridization (CGH) analysis; the loss of 19q in 19q13.2-qter was detected by loss of heterozigocity (LOH) studies in glioblastomas deletion of chromosome 4q, complete or partial gains of chromosome
20 has been described; gain or amplification of 12q14-q21 has been reported the loss of chromosome Y might be considered, when it occurs in addition to other clonal abnormalities
Genes involved and ProteinsNote � Alteration of genes involved in cell-cycle control:
it is known that the progression of the-cell cycle is controled by positive and negative regulators; some autors report alteration in cell-cycle gene expression in human brain tumors the p16 gene and the p15 gene are located in 9p21, a chromosome region commonly deleted in astrocytomas; expression of p16 gene is frequently altered in these tumors: in 33-68% of primary glioblastomas and 25% of anaplastic astrocytomas the Rb gene located on13q chromosome plays an important role in the malignant progression of gliomas the p53 gene is a tumor suppressor gene located on chromosome 17p13.1; loss or mutation of p53 gene has been detected in many types of gliomas and represents an early genetic event in these tumors overexpression of MDM2 is also seen in primary glioblastomas others oncogenes have been found to be amplified in a few cases of astrocytomas : oncogenes Gli, MYC, MYCN, MET and N-Ras � Loss or inactivation of tumor suppressor genes: in addition to p53 gene, others tumor suppression genes play a role in astrocytomas loss of chromosome 10 is the most frequent abnormality associated with the progression of malignant astrocytic tumors; more than 70% of glioblastomas show LOH on chromosome 10; amplification of EGFR is always associated with loss of chromosome 10 the PTEN gene located at the 10q23 locus is implicated more frequently in glioblastomas than in anaplastic astrocytomas another suppressor gene the MXII gene has also been located on the distal portion of chromosome 10 at the 10q24 at the 10q24-p25 locus homozygous deletion in the DMTB gene located on the region 10q25.3-26.1 have been reported in glioblastomas the LG11 novel gene located in 10p24 region is a suppressor gene rearranged in several glioblastomas tumors allelic loss of chromosome 22q wich contains the neurofibromatosis type 2, tumor suppressor gene NF2 is observed in 20-30% of astrocytomas. But another possibility is the involvement of another gene located on chromosome 22 in the tumorogenesis of astrocytomas most of these genes participate in the progression of astrocytomas (fig 1) � Expression of growth factors and growth factor receptors: the epidermal growth factor receptor (EGFR) coded by the EGFR cellular oncogene is located on human chromosome 7 at locus 7p12-p14; EGRF is amplified in 40-60% of glioblastomas; it constitues a hallmark: primary glioblastomas rarely contain EGFR overexpression; patients with anaplastic astrocytomas or glioblastomas have a poorer
prognosis when EGFR gene amplification is present; amplification could be a significant prognostic factor in these tumors over expression of PDGFR-a (platelet derived growth factor) is asociated with loss of heterozygosity of chromosome 17p and p53 mutations in secondary glioblastomas others growth factors expressed in gliomas include fibroblast growth factors (FGFs), insulin-like growth factors (IGFs), and vascular endothelial growth factor (VEGF)

Inheritance incidence of 7/105; given the variable expression of the symptoms, the actual frequency is likely to be higher; generally there is sporadic occurrence of the syndrome (85%); inheritance is mostly maternal (imprinting) with a more severe phenotype after maternal transmission
ClinicsNote clinically and genetically heterogeneous; three distinct regions on 11p15
have been associated with BWS (BWSCR1/2/3); BWSCR2 seems to be particularly associated with hemihypertrophy
Phenotype and clinics
multiple features that occur variably; most prominent is the EMG triad (exomphalos-macroglossia-gigantism): apart from the abdominal wall defects and pre- and postnatal growth abnormalities, earlobe pits or creases, facial nevus flammeus, hypoglycemia, renal abnormalities and hemihypertrophy (unilateral overgrowth) are frequently seen
Patient with Beckwith-Wiedemann syndrome. The face shows the enlarged tongue
(macroglossia), the ear the typical earlobe creases - Marcel Mannens
the increased risk for childhood solid tumours is 7.5% (thousand fold increase); tumours most frequently seen are nephroblastoma (Wilms tumour), adrenocortical carcinoma, rhabdomyosarcoma and hepatoblastoma; clinical risk factors are hemihypertrophy and nephromegaly; genetic risk factors are uniparental disomy (UPD) and H19/IGF2 imprinting defects
Treatment in general surgical correction of the abdominal wall defects and macroglossia; monitoring the glycemia during the first 3 days and early treatment of hypoglycemia (deleterious for central nervous system) is of importance to avoid further complications; frequent screening for tumour development
Prognosis clinical features tend to become less with ageing; tumour risk decreases strongly after the 4-7th year of birth
CytogeneticsInborn conditions
paternal duplications of chromosome region 11p15, maternal translocations involving chromosome region 11p15.3-p15.5
Cytogenetics of cancer
apart from chromosome 11 aberrations, multiple chromosomes are involved in tumour development; promising prognostic indicators in Wilms tumour might be chromosome 1p and 16q aberrations; tther molecular abnormalities associated with an adverse outcome in Wilms tumour are 22q allele loss or P53 aberrations
Other findingsNote in 10-20% of BWS cases, uniparental disomy of chromosome region
11p15 is seen, mostly in a mosaic form
Genes involved and ProteinsGene Name H19
Location 11p15.5 Note imprinted, maternally expressed, untranslated mRNA DNA/RNADescription the human H19 gene is 2.7 kb long and includes 4 small introns;
maternally expressed, paternal imprint ProteinDescription untranslated Expression highly expressed in endodermal and mesodermal embryonic tissues; in
adult brain, only in the pons and globus pallidus; in adult tissues, expression is primarily confined to skeletal and cardiac muscle; other tissues are down-regulated postnatal but re-expressed in tumours that express the gene during embryogenesis
Function putative tumour suppressor; proposed regulatory function for IGF2 expression (under debate)
Germinal hypermethylated in 10-20% of sporadic BWS cases; familial transmission unclear yet; loss of imprinting (LOI) can be induced in deletion mouse models
Somatic hypermethylated in 10-20% of sporadic BWS cases mostly somatic events due to UPD in mosaic form; LOI in tumours

Hereditary breast cancer IdentityNote hereditary or familiar form of breast cancerwith a familiar background Other names � site-specific breast cancer
� familiar breast-ovarian cancer Inheritance � follows an autosomal dominant pattern
� 5-10 % of all breast cancers have hereditary background � hereditary susceptibility for breast cancer has been counted to be 30-40 % of BRCA1 (see below, gene section), 10-30 % of BRCA2, less than 1 % of Tp 53, less than 1 % of PTEN and one third of unknown mutations; frequency of BRCA1 mutation is around 0.2 % in general population, 200 carriers among 100 000 individuals.
ClinicsNote hereditary breast cancer is a heterogenous entity including several
clinical variants Phenotype and clinics
"site specific breast cancer" is characterized by the predominance of breast cancer, while "hereditary breast-ovarian cancer" has neoplasms in both organs � BRCA1 mutation carrier (chromosome 17q12-21) has early age at onset, and lifetime risk for breast cancer 50 % - 85 % and ovarian cancer 15 %-45 %; about 500 different mutations have been reported; possible increased risk of prostate cancer and colon cancer � BRCA2 (chromosome 13q12-13) mutation carrier has risk for breast cancer 30 %-85 %; about 300 different mutations have been reported; it is also associated for male breast cancer (6 %) and ovarian breast cancer (10% -20%); increased risk of prostate, laryngeal cancer and pancreatic cancer. � other genetic conditions associated with increased breast cancer risk are: � Li-Fraumeni syndroma (p53 mutation on chromosome 17p13) is characterized by very early onset of neoplasms, including soft tissue sarcoma, osteosarcoma, brain tumours, leukemia, lung cancer, laryngeal cancer and adrenocorteal cancer.; lifetime risk for cancer: about 90 % for women and 70 % for men � Cowden syndroma (PTEN, 10q23) is a rare type of autosomal dominant inherited condition of multiple hamartomas with increased risk of bilateral breast cancers and thyroid tumours � Muir-Torre Syndroma ( MSH2 , MLH1), with also cancers of the gastro intestinal (GI)-tract, skin, genito urinary (Gu)-system
� Peutz-Jeghers Syndroma, with also abnormal melarin deposits, GI-polyposis, cancers of the GI-tract, uterus, ovary and testis. � Ataxia-teleangiectasia (linked to chromosome 11q21) autosomal recessive disorder with many clinical signs including increased risk for breast cancer; homozygous AT carriers have around 100-fold risk of cancer � one third of familiar breast cancers with hereditary background is still unknown; recent findings indicated that genotyping "BRCA3" locus at 13q and "BRCA2" locus at 2q may lead identifing the next mutations. � breast cancers of BRCA1 and, to lesser extent BRCA2 carriers differ from those of sporadic breast cancers: more high-grade tumours, pleomorphism, a higher mitotic count, less tubule formation, more often steroid receptor negative, DNA-aneuploid and more often higher s-phase fractions.
Treatment � prophylactic bilateral mastectomy (reduces the risk of about 90 %) and/or ovarian ablation. Chemoprevention (antiestrogens, aromataze inhibitors, retinoids) mainly in clinical trials (tamoxifen may reduce the risk about 45 %). � early detection of cancers by screening mammograms (ultrasound) yearly, palpation, transvaginal ultrasound.
Prognosis prognosis is more dependent on extent of the disease at diagnosis than on the hereditary susceptibility

Variegated aneuploidy related to premature centromere division (PCD) IdentityNote
� it has been proposed that patients with variegated aneuploidy related to PCD are homozygotes for this trait, but in several cases one of the parents do not show elevated frequency of PCD
� the term premature centromere division has also been utilized to describe an unrelated cytogenetic phenomenon, the age related loss of centromeric function in chromosome X � variegated aneuploidy has also been described in patients without PCD and patients with Roberts syndrome
Other names
(Variegated aneuploidy or mosaic aneuploidy) related to (PCD, C-anaphases,premature anaphase, premature chromatid separation or asynchrony of mitotic stages)
Inheritance � only 11 patients known � premature centromere division (PCD) without variegated aneuploidy has been shown to have an autosomal dominant inheritance, with an estimated frequency of 0.1% of the population
� a recessive inheritance with hormonal factors modifying the expression of PCD in a carrier, isodisomy of one chromosome or loss of heterozygosity has been suggested
ClinicsNote patients show a remarkably constant clinical phenotype probably due to
high cellular mortality induced by the aneuploidies; similar clinical findings have also been found in other patients with an expected increased cellular mortality (variegated aneuploidy without PCD and the "ring syndrome")
Phenotype and clinics
the clinical phenotype of the 11 patients described in the literature includes microcephaly (11/11), central nervous system (CNS) anomalies (5/6) with cerebellar defects and migration defects, mental retardation (8/9), prenatal (always noted over 23 weeks of gestation) and postnatal growth retardation (10/10), flat and broad nasal bridge (4/7), apparently low-set ears (5/8), eye abnormalities (8/10), skin abnormalities (3/9) and ambiguous genitalia in male patients (4/6); seizures have been reported in 5 patients; cancer is a major concern in the clinical management of these patients (5/11); birth weight corrected for gestational age ranges from -1.3 to -4.1 SD, birth length from -0.8 to -5.4 SD and OFC from -2.6 to -5.8
the occurrence of Wilms tumor in three patients, rhabdomyosarcoma in two others and acute leukemia in a fifth characterizes this condition as a chromosome instability disorder with a high risk of malignancy; interestingly enough, preferential loss of maternal 11p15.5 chromosome region has been repeatedly reported in Wilms tumor as well as in rhabdomyosarcoma
Prognosis although published data is incomplete, at least 4 patients have died before 2 years of age, a fifth deceased at 42 years and one patient aged 18 month has an advanced, relapsed rhabdomyosarcoma; patient's death had been related to pneumonia (one patient), leukemia (one patient), and Wilms tumor (three cases)
CytogeneticsInborn conditions
� the terms premature centromere division (PCD), C-anaphases, premature anaphase, premature chromatid separation and asynchrony of mitotic stages describe cells in division which have overcome a colchicine-induced metaphase block; the resulting mitotic configuration shows split centromeres and splayed chromatids in all or most of the chromosomes. � control individuals generally show low frequencies of PCD (up to 3% of the mitoses), which seems to have no pathological relevance, but in 0.1% of the population an elevated PCD frequency (>5%) is found in colchicine exposed lymphocyte cultures; this type of PCD shows autosomal dominant inheritance and has traditionally considered to be harmless with the possible exception of some patients with subfertility or repeated abortion. � in few patients high levels of PCD (25- 87%) are found in combination with an increased number of cells with mosaic aneuploidies, microcephaly, mental retardation and a variety of malformations; in these patients, trisomy is by far more frequent than monosomy; trisomies of chromosome 8, 18 and X predominate in lymphocyte cultures and trisomy 2, 7, 12 and 20 predominate in fibroblasts; usually, at least one of the parents shows an elevated PCD frequency (range 12.6-42.5) but not variegated aneuploidy. � high levels of PCD have been reported in skin fibroblasts (althought in at least one case no aneupoidies where found), hair-root, bone marrow and trophoblastic cells of chorionic villi; there is no data of PCD expression in amniocytes but pseudomosaicism of chromosome 7 and 21 has been reported in amniocytes; cord blood chromosome analysis in one case showed PCD and variegated aneuploidies.

Hereditary Pancreatic Cancer IdentityOther names familial pancreatic cancer
Inheritance it has been estimated that as many as 10% of pancreatic cancers have a hereditary basis; five genetic syndromes have been identified that are associated with the familial aggregation of pancreatic cancer; these include: � the second breast cancer syndrome (BRCA2), � the familial atypical multiple mole melanoma (FAMMM), � the Peutz-Jeghers Syndrome, � the hereditary pancreatitis and � the hereditary non-polyposis colorectal cancer (HNPCC) syndrome � most kindreds with familial pancreatic cancer, however, do not fall into one of these well-defined syndromes and these are referred to simply as "family pancreatic cancer."
Clinicsa generally accepted definition of familial pancreatic cancer is a kindred in which at least a pair of first-degree relatives (sibling-sibling or parent-child) have been diagnosed with pancreatic cancer; several large registries have been established to define the patterns of inheritance and genetic basis for the familial aggregation of pancreatic cancer in these kindreds; the National Pancreas Tumor Registry (NFPTR) is the largest such registry; over 260 familial pancreatic cancer kindreds have enrolled in this registry and studies of these kindreds has revealed that when followed prospectively, apparently healthy, first-degree relatives of patients with familial pancreatic cancer have an 18-fold increased risk of developing pancreatic cancer; when there are three or more family members with pancreatic cancer in a kindred, the first-degree relatives of the index patient with pancreatic cancer have a 56-fold increased risk of developing pancreatic cancer each of the five clinically recognized syndromes associated with the familial aggregation of pancreatic cancer has its own unique clinical findings
Note
� second breast cancer syndrome: the BRCA2 tumor suppressor gene is located on chromosome 13q and carriers of germline BRCA2 mutations have a significant lifetime risk of developing breast cancer (30-85%) at a young age; they are also at risk for bilateral breast cancer; BRCA2 is also associated with an increased risk of male breast cancer, ovarian cancer, prostate cancer and pancreatic cancer; the
lifetime risk of pancreatic cancer in carriers of germline BRCA2 mutations is approximately 10%; germline BRCA2 mutations are particularly common amongst individuals of Ashkenazi Jewish heritage because of a founder effect
� familial atypical multiple mole melanoma (FAMMM) syndrome has an autosomal dominant mode of transmission; most cases are caused by germline mutations in the p16 tumor suppressor gene on chromosome 9p; individuals affected with FAMMM develop multiple melanocytic nevi, some of which can be atypical; they also are at increased risk of developing melanoma and pancreatic cancer; the lifetime risk of pancreatic cancer in individuals with germline p16 mutations is about 20% � the Peutz-Jeghers Syndrome is inhertied in an autosomal dominant mode; it has recently been shown to be caused by germline mutaitons in the STK11/LKB1 gene on chromosome 19p; individuals with this syndrome typically develop multiple mucocutaneus melanin macules, harmartomatous gastrointestinal polyps and they have an increased risk of developing cancers of the gastrointestinal tract; it has been estimated that the lifetime risk of pancreatic cancer in patient with the Peutz-Jeghers Syndrome is approximately 30% � hereditary pancreatitis has an autosomal dominant mode of transmission; it is caused by germline mutations in the cationic trypsinogen gene (called PRSS1) on chromosome 7q35; affected individuals develop recurrent episodes of pancreatitis at a young age and they have an elevated lifetime risk of developing pancreatic cancers that approaches 40% � the hereditary nonpolyposis colorectal cancer (HNPCC) syndrome is caused by germiline mutations in one of the DNA mismatch repair genes (such as hMLH1 on chromosome 3 p and hMSH2 on chromosome 2p); in addition to colorectal neoplasia, affected family members have an increased risk of developing pancreatic cancer; the pancreatic cancers that arise in patients with HNPCC often have a distinct histologic appearance referred to as "medullary" histology � the ataxia-telangectasia and familial adenomatous polyposis syndromes have also been associated with an increased risk of developing pancreatic cancer, however, these associations are not well-established
Treatment currently, there are no effective methods to screen individuals at-risk for early pancreatic cancer; several studies are underway to examine the effectiveness of endoscopic ultrasound (EUS) in the early detection of pancreatic cancer
Prognosis prognosis will depend on the stage of the disease at diagnosis more than it does on hereditary sysceptibility

Li-Fraumeni Syndrome IdentityNote
Inheritance
families with Li-Fraumeni syndrome (LFS) are defined by: a proband with a sarcoma aged under 45 years, with a first degree relative with cancer under 45 years and another first or second degree relative with any cancer under 45 years or a sarcoma at any age autosomal dominant, high penetrance (100% lifetime risk in females, 75% in males)
ClinicsPhenotype and clinics no associated dysmorphologies or abnormalities
Neoplastic risk
very high � the main neoplastic risks are bone, cartilage and soft tissue sarcomas, early-onset female breast cancer, brain and spinal cord tumours, childhood adrenocortical tumours, Wilms' tumour and malignant phyllodes tumours � there is no increased incidence of a number of cancers which occur frequently within the population, such as colorectal, lung, bladder and gynaecological malignancies � some other tumour types occur rarely, but more frequently than expected; these include pancreas, peripheral nervous system, leukaemia and stomach
Genes involved and Proteins
TP53Gene Name
17p13
Description
Function
Location DNA/RNA
11 exons, the first of which is non-coding ProteinDescription p53, a 393 amino acid protein
� p53 is the most commonly mutated gene in human cancers possessing multiple properties; p53 has two major roles � firstly in cell cycle arrest, predominantly in the G1 phase of the cell cycle, but also with a role in G2 and mitotic checkpoints � secondly the induction of apoptosis (programmed cell death)
� both these are induced upon DNA damage, and the response depends on many things including the type of damage and the cell type � p53 is a transcription factor with a central sequence-specific DNA binding domain and a N-terminal transactivation domain; upon DNA damage, the level of p53 increases markedly, and the DNA-binding properties are activated; the levels of p53 are regulated primarily post-transcriptionally (including phosphorylation and acetylation)
MutationsGerminal there are over 200 published reports of germline mutations
� over 75% of families with classic LFS have a germline TP53 mutation � lower proportions of families with some features of LFS have such mutations � children with adrenocortical carcinoma have an extremely high incidence of germline mutations (over 80%) the spectrum of mutations in the germline is superficially the same as somatic mutations, but there are some significant differences
Gene Name hCHK2
Location 22q12.1 DNA/RNADescription 14 exons ProteinDescription a 543 amino acid protein with homology to Saccharomyces cerevisiae
RAD53 and Schizosaccharomyces pombe cds1. Function a protein kinase which is required for DNA damage and replication
checkpoints; CHK2 is phosphorylated by ATM, and in turn can phosphorylate p53 at serine-20; it appears that germline hCHK2 mutations are uncommon in LFS
