  1. Laboratory of Blood and Vascular Biology Laboratory of Human Genetics and Hematology Laboratory of Genome Maintenance Informatics Core • The Rockefeller University Rockefeller Phenotyping Initiative Translational Key Function Committee 8/3/2010

  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. The Case for Deep Phenotyping “We continue to depend primarily on standard disease diagnoses, which are both incomplete and imprecise, as representations of human phenotypes.” Nat. Gen. 2003, 34: 15-21

  4. The Case for Deep Phenotyping “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: 15-21

  6. Rockefeller University Bleeding History Phenotyping System • Aim: to provide a common set of tools and unified database for the collection, curation, and dissemination of standardized bleeding phenotypes • Bleeding History Questionnaires • Laboratory data entry • Query and visualization software • http://ds9.rockefeller.edu/RUBHPSR/

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

  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
