Description

The BRCA2 c.266C>T variant is predicted to result in the amino acid substitution p.Pro89Leu. This variant has been reported in individuals with breast, ovarian, and/or pancreatic cancer (Table 6, Abulkhair et al. 2018. PubMed ID: 30199306; Table 2, Schwartz et al. 2019. PubMed ID: 31432501; Table S1, You et al. 2020. PubMed ID: 32211327; Table S1, Abu-Helalah et al. 2020. PubMed ID: 33067490). The vast majority of these studies interpreted this variant as uncertain significance. It has also been reported in healthy control individuals (Supplementary Data, Momozawa et al. 2018. PubMed ID: 30287823; Table S1, Dong et al. 2020. PubMed ID: 32467295). This variant is reported in 4 of ~251,000 of alleles in gnomAD (http://gnomad.broadinstitute.org/variant/13-32893412-C-T) and is interpreted as uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/409565/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
