Description

This frameshift variant alters the translational reading frame of the BRCA2 mRNA and causes the premature termination of BRCA2 protein synthesis. The frequency of this variant in the general population, 0.000054 (7/128928 chromosomes, http://gnomad.broadinstitute.org), is consistent with pathogenicity. In the published literature, the variant has been reported in individuals with breast cancer (PMID: 9429140 (1997)), ovarian cancer (PMID: 29084914 (2018), 30322717 (2018), 31263571 (2019)), colorectal cancer (PMID: 27978560 (2016)), and pancreatic cancer (PMID: 31948886 (2020), 32853339 (2021)). Based on the available information, this variant is classified as pathogenic.

Description

The BRCA2 c.7069_7070del; p.Leu2357ValfsTer2 variant (rs80359636), also known as 7297delCT, has been reported in multiple individuals with early onset breast or ovarian cancer (Caux-Moncoutier 2011, Cunningham 2014, Garvin 1997, Zhang 2011). It is listed as pathogenic in ClinVar (Variation ID: 38082) and is observed 7 times in the Genome Aggregation Database (7/276,822 alleles). This variant causes a frameshift by deleting two nucleotides, so it is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Based on available information, the variant is considered to be pathogenic. References: Caux-Moncoutier V et al.
