GA4GH Variation Representation Specification

The Variation Representation Specification (VRS, pronounced “verse”) is a standard developed by the Global Alliance for Genomic Health to facilitate and improve sharing of genetic information. The Specification consists of a JSON Schema for representing many classes of genetic variation, conventions to maximize the utility of the schema, and a Python implementation that promotes adoption of the standard.
