age his mental age was evaluated as being 5months.
His feeding difficulty continued and hesuffered frequently from dehydration. His ab-domen, lumbar region, and pelvis remainedremarkably underdeveloped. His maximumlifetime weight was 6-9 kg aged 6 years 2months. Subsequently, he suffered repeatedlyfrom fever, vomiting, and dehydration anddied at the age of 8 years 7 months. Hisheight (crown to rump) at death was 49 0 cm,weight 4-96 kg, and head circumference48-2 cm. At necropsy, regurgitant oeso-
phagitis, a poorly developed small intestine,a small, thick walled (approximately 9 mm)urinary bladder, and small undescendedtestes were found.The ethics of keeping such a child alive for
eight years may seem to be questionable.However, passive euthanasia of such a case
as this patient would not be readily acceptablein Japan.

Genetics and Alcoholism. EvelyneDumont-Damien, Michel Duyme. Paris:Editions INSERM. 1993.
In the latter part of last century many heldthe view that alcoholism was inherited. Thependulum of opinion swung, and by the1960s there was little doubt in the minds ofthe great majority of its investigators that theorigin of alcoholism was psychosocial. Today,with the developing knowledge in biology andespecially in the genetics of behaviour, it ispossible to contemplate some genetic con-
tribution to its aetiology. For this several fac-tors are responsible. Numerous diseases areknown which result from a combination fo
genetic and environmental elements. For ex-ample, one parallel to alcoholism is cancer ofthe lung, where the environmental factor isclear but only a proportion of heavy smokersdevelop the disease. Genetic studies have be-come possible, for the alcoholism phenotypehas been better defined, and there are manygenetic markers which allow a search for thelocation of genes producing susceptibility toany disease.The authors of this book have drawn to-
gether almost all the accessible publicationson genetic studies of alcoholism and havereviewed them critically. Their object is tomake a balanced appraisal of present know-ledge. They envisage alcoholism as a complexbehavioural feature, and apply to it the meth-ods of genetic analysis of behaviour.
Immediately in chapter 1 the principalproblems that hinder genetic analysis aresquarely faced: problems of definition, meas-urement of the phenotype, lack of clarity ofthe underlying biological mechanisms, andtherefore of possible functional markers. Itconcerns types of alcoholics, aetiologicalmodels, measures of alcoholism, and the sev-eral hypotheses involving neurobiology. Thechapters that follow summarise the differenttypes of study.
Chapter 2 is devoted to family studies, ofwhich there are approximately 200, com-paring relatives of different degrees sharingsimilar family environments. They show fa-milial concentration of alcoholism, so thatthe risk is greater for a person, particularly fora male, who has numerous alcoholic relatives,and they suggest an aetiological heterogeneitymanifesting in variations in the precosity andseverity of the condition. The authors identifytopics on which future research could mostprofitably concentrate.
Chapter 3 draws together the numeroustwin studies, 34 published in the period 1939to 1991. These do not exclude genetic in-fluence and indeed strongly suggest to theauthors a multifactorial aetiology, the geneticcontribution to which is most apparent inmale twins who are alcohol dependent.The next chapter is devoted to adoption
studies, usually considered essential for dis-tinguishing genetic and enviromental effects.There have been about a dozen such studies,though the authors show that most of theseare biased and use research designs that arenot very informative. One finding emergesclearly from the subgroup of studies whichare less open to criticism, namely a link be-tween the biological father and his sonbrought up by adoptive parents. These sonsknew nothing of the behaviour of their bio-logical fathers; their biological mothers as wellas their two adoptive parents were effectivelynon-alcoholic. These findings do not ofcourse provide formal proof, but they favourthe hypothesis of a transmission of some gen-etic factor from the father to the son. Theresult supports the suggestion from the familyand twin studies that there is a dominatingmale influence.The studies in chapter 5 complement these
classical approaches, for they deal with sibsand half sibs brought up apart and unrelatedchildren brought up together. There are onlyfour studies of this type. Criticisms can belevelled at all, especially in the small numberof variables considered or the lack of rigourin their specification, so their findings canonly be taken as indications. But despite theirdrawbacks they support the interpretationfrom the investigations in the previous chap-ters that there is some genetic influence onalcoholism.
The crucial proof that there is a geneticcontribution to the aetiology of alcoholismwill come from the discovery of one or moremarkers, genes, or DNA segments. Thesearches for these have been numerous andthe authors restrict their survey to those stud-ies of characters whose chromosomal loc-ations are known. There are 140 such studies,covering more than 50 markers, the majoritybeing searches for association (to establishrelative risks) and only a few using linkage(to establish location). The studies as a whole,dealt with in chapter 6, show that to datethere is no certainty that any of the charactersanalysed is a marker for alcoholism. But thesestudies give valuable pointers to the meth-odological precautions to be taken and thepaths to be followed in future investigations.The book closes with a series of 14 ap-pendices, dealing in detail with key topicsmentioned in earlier chapters but where fullerconsideration would have interrupted the flowof the argument. These topics include forexample the principal definitions of al-coholism, its classification and typologies,clinical and biological indicators, and ae-tiological models of alcoholism proposed inthe period 1972 to 1988, ending with thoseof Donovan and of Radouco-Thomas. Thelist of some 850 references covers only thosepublished in English or French.The conclusions of the authors after their
critical examination of hundreds of publishedworks is that it is not yet definitely es-tablished that genetic differences betweenpersons account for their variation in be-haviour regarding the pathological taking ofalcohol. Nevertheless there are strong in-dications that at least in some persons thereis a genetic vulnerability to the abuse of,or dependence on, alcohol, especially maleswhose father and several ascendant relativeswere alcoholic. The task now for genetic epi-demiologists is to find the genes that pre-dispose to the different types of alcoholism.
This book is positively written. From itscritical appraisal of exisiting works, and theirlack of conclusive findings, it draws lessonsas to the points that future studies shouldattack and the methodological weaknessesthat should be avoided. It is moreover care-fully written, well balanced, well organised,a meticulous appraisal of the numerous worksexamined by the authors. It is the most com-prehensive survey ofthe subject yet produced,and one which any investigator of the subjectcannot afford to ignore.

Diagnostic Criteria for NeuromuscularDisorders. Editor A E H Emery. (Pp 72.)UK: ENMC Publishing. 1994.
As Research Director for the EuropeanNeuromuscular Centre (ENMC), Baarn,The Netherlands, A E H Emery has par-ticipated in around 30 workshops designedto co-ordinate and encourage European re-search groups involved in the isolation andcharacterisation of the genes responsible fordiverse neuromuscular disorders. This pub-lication is introduced as a discussion docu-ment and presents, with some modifications,a series of articles which have appeared inNeuromuscular Disorders (Pergamon Press)setting out the diagnostic criteria proposed ateach workshop. At the times of a number of

the workshops, the relevant genes had beencloned and this is reflected in the relevantchapters; for instance the diagnosis ofDuchenne muscular dystrophy (DMD) isdefinite "where almost no dystrophin is dem-onstrable in a muscle biopsy specimen" orthere is "a Duchenne-type mutation withinthe dystrophin gene". Likewise the sectionon myotonic dystrophy lists amplification(>45) of the trinucleotide repeat sequence inthe DM-kinase gene on chromosome 19 inthe diagnostic criteria. There is an attemptin some chapters to comment on currentdiagnostic approaches for DNA analysis, forexample, multiplex PCR, SSCP, mRNA(RT-PCR), and most recently the protein trun-cation test in DMD; the shortened 4q35linked EcoRI fragment detected by pl3E-1 1in facioscapulohumeral muscular dystrophyand the chromosome 17pll.2 duplicationassociated with Charcot-Marie-Tooth diseasetype IA. In a text of only 72 pages the com-ments are of necessity brief and the reader isleft with the reference lists to identify furtherreading. The reference lists range from noentries (the section on Rare NeuromuscularDisorders) to 24 (Limb Girdle Muscular Dys-trophy) with two (Myotonic Dystrophy, Con-genital Muscular Dystrophy) citing singlereferences. The coverage ofpublished reportscould have been better standardised acrossthe sections and perhaps one or two keyclinical references could have been includedin each section.
It is unfortunate that some "chapters"begin with tables or lists (Duchenne/Beckerdystrophies, myotonic dystrophy, spinal mus-cular atrophy). The more traditional in-troduction to Limb Girdle MuscularDystrophy (K M Bushby) is eminently morereadable. Likewise the use of the ab-breviations "I", "E", and "C" for inclusioncriteria, exclusion criteria, and comments re-
spectively, in only some of the chapters isirritating. Putting aside these comments onformat, the answer to the question ofwhetherthis slim volume "will be useful to cliniciansand scientists engaged in this field of re-search" will depend on the individual person'sreason for consulting the chapters. The chap-ters are not intended to be reviews of theclinical manifestations nor of the applicationof molecular techniques to the diagnosis ofthese disorders. Unified clinical criteria forthe diagnosis of disorders are useful, par-ticularly in studies using linkage analysis,although the availability of computer pro-grammes such as the HOMOG series allows,to an extent, for genetic heterogeneity. Thechapters do present some fairly fundamentalfeatures on which the diagnosis of these dis-orders can be made but the layouts of thechapters do not make an easy format for useby a junior doctor faced with a patient witha neuromuscular problem.The contribution made by the ENMC to
furthering collaborations between the dis-parate research teams working on thesedisorders in Europe should not be un-derestimated. The standardisation of thediagnostic criteria to be used by these groupswhen identifying affected persons and fa-millies and when making resources availableto others was important. The publication ofsuch criteria (in Neuromuscular Disorders) en-abled them to be used as a standard referenceby the research groups and thus to cut downon unnecessary duplication in subsequent re-ports. This publication aims to make thesecriteria available to a wider audience. Un-fortunately the format and content of thechapters makes it difficult to identify who itwill best serve.
