Variant lookup
ClinVar, gnomAD, Ensembl VEP, and AlphaMissense annotations for any rsID or HGVS notation.
Two ways to look up a variant
1. Use the GenoLens Chrome extension
Highlight any rsID (e.g.
rs334) on any webpage and a tooltip appears with all 15 data sources. No copy-paste, no tab-switching.2. Visit dbSNP directly
For a quick lookup of a specific rsID, dbSNP at NCBI is the canonical reference: ncbi.nlm.nih.gov/snp ↗
Searchable variant pages — coming soon
We're building dedicated pages for the ~50,000 ClinVar pathogenic and likely-pathogenic variants, indexed for Google search. Each page will surface ClinVar review status, gnomAD allele frequencies, AlphaMissense pathogenicity, and the genes & diseases linked to that variant.
In the meantime, the extension covers all of this on any webpage.
