2 The Case for Deep Phenotyping “Our capacity to undertake [genome-wide] projects will probably not be the limiting step in elucidating the genetic basis of common diseases. Instead, we may be held back by our inability to specify precisely the phenotypes… in those individuals whose genomes we investigate.” Nat. Gen. 2003, 34: 15-21

3 “We continue to depend primarily on standard disease diagnoses, which are both incomplete and imprecise, as representations of human phenotypes.” Nat. Gen. 2003, 34: The Case for Deep Phenotyping

4 “Furthermore, phenotyping is still rooted in clinical traditions, which vary greatly between medical specialties and between different locales; it does not yet have the systematization or throughput to match the worldwide genotyping studies that are envisioned.” Nat. Gen. 2003, 34: The Case for Deep Phenotyping

15 Bleeding History Phenotyping Project Phenotyping healthy individuals Phenotyping individuals with bleeding disorders Deriving bleeding “scores” to maximize diagnostic and prognostic discrimination Streamlining questionnaires for primary care physicians and in the developing world Database mergers Natural language processing Mobile Web development

16 International Fanconi Anemia Registry (IFAR) Established in 1982 to study a large number of patients exhibiting the full spectrum of diverse features of FA. Data-rich starting point: – 28 year compendium of demographic, cytogenetic, medical history, hematologic, genealogic, treatment and transplantation data from over 1400 patients

17 Fanconi Anemia Mutation Database Established in 1998 as a cooperative effort to accelerate the availability of information on mutations in these important cancer- predisposing genes

18 The problem: An inability to grasp the complete picture Diverse data sources unlinked Current IFAR database stored in rigid, inflexible legacy system Lack of a complete description of the knowledge base and data relationships Inability to merge genotype and phenotype/demographic information Desire to expand the range and specificity of phenotype data Desire to include new information (i.e. next gen. sequencing) as data becomes available

19 Ontology- based Filtering Graph Consolidated IFAR database Data query and representation Enhanced International Fanconi Anemia Registry Fanconi Anemia Ontology Original IFAR database Mutation database Novel phenotyping instrument

23 Conclusions The Rockefeller Phenotyping Inititative seeks to develop novel methods for collecting and characterizing phenotypes, with the goal of improving the ability to identify genotype- phenotype correlations As part of the Rockefeller CTSA renewal, we have offered to undertake one additional phenotyping project per year on behalf of the CTSAs
