We updated our gene constraint metrics following the release of gnomAD v4.0. gnomAD v4.0 expanded the scale of our constraint calculations…

Today we are pleased to announce the incorporation of cumulative counts of gnomAD individuals carrying pairs of rare co-occurring variants within genes in the gnomAD v2 browser, across various allele frequencies and functional consequences. These counts can be used to evaluate how frequently rare variant co-occurrence is observed in a large reference population. We envision that this data will aid the medical genetics community in interpreting the clinical significance of rare co-occurring variants found in patients, in the context of autosomal recessive disease. This feature builds off of our variant co-occurrence (inferred phasing) work (see “Variant Co-Occurrence (Phasing) Information in gnomAD”).
