OMIM is a free-text disease description source

OMIM genes ZFIN mutant genes FlyBase mutant genes Strategy: use shared genes as proof of principle
14
Annotate phenotypes in human, zebrafish, and fly Annotate human phenotypes triple blind Compare annotations + + ZFIN BBOP FlyBase OBD
16
~10% of the annotations for 1 gene
17
Curator 1 Curator 2 Curator 3 Annotations vary among curators
18
Curator 1Curator 2Curator 3 Ontologies support comparisons
19
Subsumption reasoning for similarity scoring Information content (IC) is calculated based on depth within the ontology and annotation frequency Similarity is calculated based on ratio of IC values

22
All alleles are significantly more similar to alleles of the same gene than to alleles of other genes p<0.0001
23
shha query against zebrafish returns signaling pathway members Annotations can identify other pathway members Similarity search for zebrafish shha t4/t4 identifies pathway members
24
A search for phenotypes similar to: Human EYA1 variant OMIM:601653 MP:deafness = E = Sensory perception of sound Q = absent Human phenotypes identify mutations in orthologous model organism genes
25
A search for phenotypes similar to: Human EYA1 variant OMIM:601653 MP:deafness = E = Sensory perception of sound Q = absent returns: Mouse Eya1 bor/bor and Eya1 tm1Rilm/tm1Rilm E = Sensory perception of sound Q = decreased Human phenotypes identify mutations in orthologous model organism genes
