Importance of phenotype information

disease

genotype

phenotype

Capture info in databases

Structured (=coded) rather than free text data

Page 3: Day 3 Sijmons Using HPO fenotyping

“Football”    as free textComputer cannot tell the differenceData content should be unambiguous

Page 4: Day 3 Sijmons Using HPO fenotyping

Simply a list of codes is not the best solution……

if ‘the computer’ knows the relationships between the codes your code system in much more 

powerful

Move up and down the tree’s to

‐ Select more general groups of patients for research / care

‐ Find your syndrome in NGS data‐ sharp versus broad

Is a computational representation of a domain of knowledge 

based upon a controlled, standardized vocabulary for describing entities 

and 

the semantic relationships between them 

This type of code system is called an ‘Ontology’

The HPO aims to act as a central resource to connect several genomics datasets with the diseasome.

The Human Phenotype Ontology

• Aims to provide a standardized vocabulary of phenotypic abnormalities encountered in human disease. 

• 10,088 classes (terms) describing human phenotypic abnormalities and 

• 13,326 subclass relations between the HPO classes. In addition 

• Logical definitions for 46% of all HPO classes using terms for anatomy, cell types, function, embryology, pathology, etc. Goal: interoperability with several resources, annotat

• HPO annotations of 7,278 human hereditary syndromes

Different types of phenotypic abnormalities

‘Class’ of phenotype  HPO exampleMorphological abnormality  Arachnodactyly (HP:0001166)

Abnormal process (organ)  Epistaxis (HP:0000421)

Abnormal process (cellular)  Abnormality of Krebs cycle metabolism 

(HP:0000816)

Abnormal laboratory finding  Glycosuria (HP:0003076)

Electrophysiological abnormality  Hypsarrhythmia (HP:0002521)

Abnormality by medical imaging  Choroid plexus cyst (HP:0002190)

Behavioral abnormality  Self‐mutilation (HP:0000742)

International Classification of Diseases (ICD)

Is an Ontology

The International Classification of Diseases (ICD) is the standard diagnostic tool for epidemiology, health management and clinical purposes. This includes the analysis of the general health situation of population groups. It is used to monitor the incidence and prevalence of diseases and other health problems.

Order from VWS:as of Januari 2015

Put ICD‐10 codeOn every hospital 

bill

Page 29: Day 3 Sijmons Using HPO fenotyping

Thesaurus pushed by Government

Have ContactedProfessional Societies

(domains)Incl Genetics

To help modify/expand Diagnostic Thesaurus

Page 30: Day 3 Sijmons Using HPO fenotyping

Proposal to Koepel

• Enrich Diagnostic Thesaurus (SNOMED) with cleaned codes from CINEAS, HPO (+ Orphanet) in 2015

• Discontinue CINEAS after 2015 (keep legacy codes for future research in old cohorts)

• and Switch for phenotype coding to Thesaurus 

• Develop local IT solutions for the switch• Develop logistics for cleaning/updating codes (engage society members)

(3) Toekomst CINEAS

‐ In de lucht houden zolang er geen goede (Internationale) opvolger/alternatief is

‐ Als die er wel is‐ Kosten (goedkoper?)‐ Beheer ?‐ “ koppelbaarheid” , “ universeel karakter” ?‐ Beschikbaar houden van alle CINEAS codes voor wetenschap, kliniek etc om

te kunnen blijven zoeken in oude data (Goedkoop)

(3) Toekomst CINEAS‐ VOORSTEL tussen nu en eind 2015
