Variation Representation Specification (VRS) v2.0 establishes a standardised computational language that enables integration of variant evidence across different sequence collections used by resources in order to advance a broader framework for sharing variant knowledge. Product development of VRS v2.0 was led by Alex Wagner (Nationwide Children’s Hospital) and Larry Babb (Broad Institute of MIT and Harvard).
