Description

The CHEK2 c.1100del (p.Thr367MetfsTer15) change causes a frameshift and the creation of a premature stop codon. This change is predicted to cause protein truncation or absence of the protein due to nonsense mediated decay (PVS1). This variant has been widely reported to be associated with cancer susceptibility, including significant associations with increased risk of breast cancer in large meta-analysis studies (odds ratios ~2-5, PMID: 18172190, 22994785). This variant has also been reported in individuals with colon, prostate, gastric, kidney, and thyroid cancer (PMID: 14612911, 15087378, 15492928, 16880452, 21807500, 23296741, 25431674, 25583358, 26884562). This change has an overall frequency of 0.21% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/) and has been described as a founder variant in Northern European populations (PMID: 15087378). In summary, this variant meets criteria to be classified as pathogenic with evidence indicating lower penetrance.
