Whatis the problem ? Computers are not smart enough…. • The following descriptions mean the same thing to you: • generalizedamyotrophy • generalizedmuscle atrophy • muscularatrophy, generalized • But your computer thinks they're completely unrelated
Phenomes: a continuum • Disease • Malformation syndrome • Morphologicalanomaly • Biologicalanomaly • Clinical syndrome • Particular clinical situation • No type: waiting to have a type attributed
Orphan Diseasome An Orphan Diseasomepermits investigators to explore the orphan disease (OD) or rare disease relationships based on shared genes and shared enriched features (e.g., Gene Ontology Biological Process, Cellular Component, Pathways, Mammalian Phenotype). The red nodes represent the orphan diseases and the green ones the related genes. A disease is connected to a gene if and only if a mutation which is responsible of the disease has been identified on this gene. http://research.cchmc.org/od/01/index.html
UMLS = Unified Medical Language System • ICD = International Classification of Diseases • Since 1863 by WHO • Used by most countries to code medical activity, mortality data • MeSH = Medical Subject Headings • controlled vocabulary thesaurus used for indexing articles for PubMed by National Library of Medicine (USA) • SnoMed CT = Systematized Nomenclature of Medicine--Clinical Terms • clinical terminology by the International Health Terminology Standards Development Organisation (IHTSDO) in Denmark • Used in the USA and a few other countries • MedDRA = Medical Dictionary for Regulatory Activities • medical terminology to classify adverse event information associated with the use of medical products • by the International Federation of Pharmaceutical Manufacturers and Associations (IFPMA)
Differentresources, different terminologies (e)HR: SNOMED CT Others? Free text Mutation/patient registries, databases: HPO LDDB PhenoDB Elements of morphology Others? Free text? Tools for diagnosis: HPO LDDB Orphanet
Eachterminology has a purpose–drivenapproach • Indexinghealthstatus of individual patients for health management (SnoMED) • Detailed, focus on manifestations and complaints • Adapted to clinical habits • Analyticalapproach • Indexinghealthstatus of individual patients for statisticalpurpose in public health (ICD) • More agregated, interpretedphenotypicfeatures • Agregated concepts • Unambiguous to avoidblanks
Purpose–drivenapproach (2) • Indexinghealthstatus of individual patients for clinicalresearchpurpose(HPO / PhenoDB / Elements of morphology) • Highlydetailed to fit with the research questions • Specific terminologies developed for disease-specific patient registries • Indexinghealthstatus of individual patients for retrievingpossible diagnoses (LDDB,POSSUM,Orphanet) • Agregated concepts • Requires a judgement of clinicians about phenomic expressions that are relevant • Unambiguous to avoidblanks
Convince the terminologies to converge in someway…. • Sept 2012: start of mappings (Orphanet) • EUGT2 – EUCERD workshop (Paris, September 2012) • ICHPT workshop (ASHG, Boston, October 2013) • Selection of 2,300 coreterms LDDB Elements of Morphology POSSUM SNOMED CT (IHTSDO) ICD (WHO) DECIPHER PhenoDB Orphanet HPO
Phenotypeterminologyproject • Aims: • Mapcommonlyusedclinical terminologies (Orphanet, LDDB, HPO, Elements of morphology, PhenoDB, UMLS, SNOMED-CT, MESH, MedDRA): • automaticmap, expert validation, detection and correction of inconsistencies • Findcommontermsin the terminologies • Produce a coreterminology • Common denominatorallowing to share/exchange phenotypic data betweendatabases • Mapped to every single terminology
MappingTerminologies • Orphanet: 1357 terms (Orphanet database, version 2008) • LDDB: 1348 dysmorphologicalterms (Installation CD) • Elements of Morphology: 423 terms (retrievedmanuallyfrom publication AJMG, January 2009) • HPO: 9895 terms (downloadbioportal, obo format, 30/08/12) • PhenoDB: 2846 terms (given in obo format, 02/05/2012) • UMLS: (version 2012AA) (integratingMeSH, MedDra, SNOMED CT)

Workshop on 21-22 October 2013 in BostonSuccess! • Reviewed 2736 terms appearing 2 or more times in the 6 terminologies in 17 hours • 2302 terms chosen, including preferred term • Definitions are from Elements of Morphology if available, and HPO/Stedman’s Medical Dictionary, if not • List of terms, mapping to HPO, PhenoDB, Elements of Morphology will be available at http://ichpt.org by January 2015. • All tools will map to this terminology to allow interoperability among resources
Adoption of a core set of >2,300 terms common to all terminologies Workshop of validation, Boston 21-22 October 2013 • Workshop supported by HVP and EuroGenTest • Organized by AdaHamosh • Expert review of the initial proposal • Selection of 2,370 terms • Decision to propose them for adoption by all terminologies • Establishment of the International Consortium for Human Phenotype Terminologies – ICHPT • Publication on the IRDiRC website with definitions from • HPO • Elements of morphology Workshop on Terminologies for RD – Paris, 12 September 2012 • Many terminologies in use to describe phenomes - No interoperability • Joint EuroGenTest and EUCERD workshop • Organized by SégolèneAymé • Agreement to define a core set of terms common to all terminologies and a methodology • Core set identified by cross referencing • HPO • PhenoDB • Orphanet • UMLS: MeSH, MedDRA, SnoMed CT • LDDB • Elements of morphology
COMPUTERS ARE NOT SMART From a terminology to an ontology
Why ontologies are needed ? • Ontologies are representations of the knowledge in a waywhichisdirectlyunderstandable by computers • Ontologies allowreasoning • Ontologies define the objects AND the relationshipbetween the objects • Duchenne musculardystrophy (disease) Is a neuromusculardisease (group of diseases) • Schistosomias (disease) Is a cause ofanemia (manifestation)
Standardization of Phenotype Ontologies Workshop Sympathy, 19 Apr 2013, Dublin Organized by IRDiRC, supported by the University of Dublin, Forge and EuroGenTest Conclusion: Adopt HPO & ORDO & cross-reference with OMIM
