INITIATIVES TO SPEED UP DATA SHARING 20
21
Rational Research produces an enormous amount of data If shared, will facilitate the development of diagnostics and treatments while ensuring efficient utilization of scarce resources Resources include patient and family material (extracted DNA, cell lines, pathological samples), technical protocols, informatics infrastructure, and analysis tools Datasets include phenotypes, genomic variants, other ‘omic’ data, natural histories, and clinical trial data… 21
22
Barriers to Data Sharing Technical and Financial issues Storing terabytes…Securing data Providing the logistics for sharing data Statistical and algorithmic issues to combine datasets Ethical and Legal issues Data across public and private networks Pricacy protection at national level Cultural issues Reluctance to share data from researchers/ Institutions/Regulatory bodies 22
23
A ClearingHouse of Data Standards is in development at IRDiRC Five main fields of application Standards in Genomics and other OMICS Standards in Phenotyping Standards in Outcome Measures for clinical trials Standards in Human Data Registration Open-access Data Repositories to store data Alignment with other efforts to ensure interconnection and shareability between data RD-Connect PCORI, Comete ELIXIR, BD2K, Data FAIRport 23
24
PhenoTips and PhenomeCentral Repository of data Hub for data sharing CareforRare, RDConnect NIH undiagnosed patients 24 Open Acess Data Repositories ClinVar and ICCG Public archive of variants and assertions about significance NCBI resource Decipher Database of Chromosome imbalances and phenotypes Using Ensembl resources Sanger Institute Wellcome Trust
25
INITIATIVES TO SPEED UP DATA MINING 25
26
Rational Make the most of remarkable advances in the molecular basis of human diseases dissect the physiological pathways improve diagnosis develop treatments Make rare diseases visible in health information systems to gain insight into them to access real life data already collected Improve coding of RD whichever coding system used Cross-reference coding systems: Orpha nomenclature, ICD10, MeSH, SnoMed-CT, MedDRA
27
What is the problem ? Computers are not smart enough…. The following descriptions mean the same thing to you: generalized amyotrophy generalized muscle atrophy muscular atrophy, generalized But your computer thinks they're completely unrelated 27
28
28 Phenomes: a continuum Group of phenomes « Disorder » level Subtypes Top of classification = System disorder Group Clinical criterion Disease, syndrome, condition,anomaly… Etiological Clinical Histopathological… No type: waiting to have a type attributed Disease Malformation syndrome Morphological anomaly Biological anomaly Clinical syndrome Particular clinical situation
30
Orphan Diseasome http://research.cchmc.org/od/01/index.html An Orphan Diseasome permits 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.
31
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)
32
Different resources, different terminologies (e)HR: SNOMED CT Others? Free text (e)HR: SNOMED CT Others? Free text Mutation/patient registries, databases: HPO LDDB PhenoDB Elements of morphology Others? Free text? Mutation/patient registries, databases: HPO LDDB PhenoDB Elements of morphology Others? Free text? Tools for diagnosis: HPO LDDB Orphanet Tools for diagnosis: HPO LDDB Orphanet
33
Each terminology has a purpose– driven approach Indexing health status of individual patients for health management (SnoMED) Detailed, focus on manifestations and complaints Adapted to clinical habits Analytical approach Indexing health status of individual patients for statistical purpose in public health (ICD) More agregated, interpreted phenotypic features Agregated concepts Unambiguous to avoid blanks
34
Purpose–driven approach (2) Indexing health status of individual patients for clinical research purpose (HPO / PhenoDB / Elements of morphology) Highly detailed to fit with the research questions Specific terminologies developed for disease-specific patient registries Indexing health status of individual patients for retrieving possible diagnoses (LDDB,POSSUM,Orphanet) Agregated concepts Requires a judgement of clinicians about phenomic expressions that are relevant Unambiguous to avoid blanks
35
HOW TO MAKE ALL THESE TERMINOLOGIES INTER-OPERABLE ? 35
36
Convince the terminologies to converge in some way…. Sept 2012: start of mappings (Orphanet) EUGT2 – EUCERD workshop (Paris, September 2012) ICHPT workshop (ASHG, Boston, October 2013) Selection of 2,300 core terms PhenoDB HPO Orphanet LDDB Elements of Morphology POSSUM SNOMED CT (IHTSDO) ICD (WHO) DECIPHER
37
Phenotype terminology project Aims: Map commonly used clinical terminologies (Orphanet, LDDB, HPO, Elements of morphology, PhenoDB, UMLS, SNOMED-CT, MESH, MedDRA): – automatic map, expert validation, detection and correction of inconsistencies Find common terms in the terminologies Produce a core terminology – Common denominator allowing to share/exchange phenotypic data between databases – Mapped to every single terminology
38
Mapping Terminologies Orphanet: 1357 terms (Orphanet database, version 2008) LDDB: 1348 dysmorphological terms (Installation CD) Elements of Morphology: 423 terms (retrieved manually from publication AJMG, January 2009) HPO: 9895 terms (download bioportal, obo format, 30/08/12) PhenoDB: 2846 terms (given in obo format, 02/05/2012) UMLS: (version 2012AA) (integrating MeSH, MedDra, SNOMED CT)
39
Tools OnaGUI (INSERM U729): ontology alignment tool – Work with file in owl format – I-Sub algorithm: detect syntaxic similarity – Graphical interface to check automatic mappings and manually add ones Metamap (National Library of Medicine): a tool to map biomedical text to the UMLS Metathesaurus Perl scripts : format conversion, launching Metamap, comparison of results…
40
Comparison of mappings and deduction Perl script to compare all the mappings and infer mappings of non-Orphanet terminologies Eg: Orphanet ID XX mapped to YY in HPO and ZZ in LDDB -> deduction: YY and ZZ should probably map Retrieve HPO mappings versus UMLS, MeSH First figures: LDDBEl.

First list of common terms Present in at least 2 terminologies Definition of rules for nomenclature Addition of terms present in each terminology as synonyms
43
Workshop on 21-22 October 2013 in Boston Success! 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.http://ichpt.org All tools will map to this terminology to allow interoperability among resources
44
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 Ségolène Aymé 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 44 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 Ada Hamosh 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
45
FROM A TERMINOLOGY TO AN ONTOLOGY COMPUTERS ARE NOT SMART 45
46
Why ontologies are needed ? Ontologies are representations of the knowledge in a way which is directly understandable by computers Ontologies allow reasoning Ontologies define the objects AND the relationship between the objects Duchenne muscular dystrophy (disease) Is a neuromuscular disease (group of diseases) Schistosomias (disease) Is a cause of anemia (manifestation) 46
47

THEY CAN HELP REPURPOSE DRUGS COMPUTERS ARE VERY SMART 50
51
Rational: Make optimal use of molecules already known Drug Repositioning or Repurposing is a strategy used to generate new or additional value for a drug, by targeting diseases other than those for which it was originally intended Address unmet medical needs Reduce time to market due to provided information on Unbiased clinical safety and efficacy data Add value to exiting porfolio Increase drug pipeline Decrease R&D failure risks Decrease development costs Creates new revenue potential 51
52
Graph Theory Enables Drug Repurposing Gramatica et Al.: PLOS one, Vol 1 e84912, 2014 23 Million articles from PubMed Possible to link the gathered information on drugs, physiological pathways and resulting biological activities with the pathophysiological signs & symptoms of diseases Possible to rank the matches in order to identify the most promising leads 52
