RCV002033601 | SCV002273122 | likely pathogenic | Hereditary breast ovarian cancer syndrome | 2022-11-29 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 3076 of the BRCA2 protein (p.Gly3076Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with BRCA2-related conditions. ClinVar contains an entry for this variant (Variation ID: 1487627). Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (PMID: 33609447) indicates that this missense variant is expected to disrupt BRCA2 function. Experimental studies have shown that this missense change affects BRCA2 function (PMID: 29394989). This variant disrupts the p.Gly3076 amino acid residue in BRCA2. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 11149425, 12569143, 19043619, 22711857, 23108138, 29161300, 29394989, 30078507, 30254663; 32814805)). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. |
