SNP Terminology development with VISTA

...

Designing a genomic variant ontology for common use within the open i2b2 community poses a unique challenge.   Variants may be defined across several domains:  dbSNP rs number, HGVS name, or gene/flanking sequence pairs. It is often difficult to know if variants from different domains are in fact equivalent.  This project investigates ways to form a common basis for describing variants.

The project also examines necessary features required for display and comparison of genomic variants within external tools.   An application has been developed to show interactive capability within the VISTA suite of visual analysis and functional annotation tools.
