Importance of phenotype information
disease
genotype
phenotype
Capture info in databases
Structured (=coded) rather than free text data
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
inclusion criteria
etc
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’
Human Phenotype Ontology (HPO) www.human‐phenotype‐ontology.org
Köhl et al (Peter Robinson’s Group) Nucl. Acids Res. 2014
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.

Not suited for detailed recording of diagnosis / phenotypes
SNOMED CT = ‘Systematized Nomenclature of Medicine – Clinical Terms’
Is an Ontology
Is a comprehensive clinical terminology, originally created by the College of American Pathologists (CAP) and, as of April 2007, owned, maintained, and distributed by the International Health Terminology Standards Development Organisation (IHTSDO), a not‐for‐profit association in Denmark.

Thesaurus pushed by Government
Have ContactedProfessional Societies
(domains)Incl Genetics
To help modify/expand Diagnostic Thesaurus
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)
SSAGA, symptom‐ and sign‐assisted genome analysis
• matches 227 clinical termsto
• 591 recessive genetic diseases with pediatric presentations
• helps interpret WGS results

‐ 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
