Overview

NCBI database of single nucleotide polymorphisms and other genetic variants.

Domain: genetics.

Source: https://ftp.ncbi.nlm.nih.gov/snp/latest_release/.

Canonical variant reference used to harmonise variants across all other namespaces.

Look up an rsid by rsid; resolve coordinates by filtering on assembly + chromosome + position.

Always filter on assembly (GRCh37 or GRCh38) — positions and alleles are assembly-specific.
