The BRCA2 c.9227G>A; p.Gly3076Glu variant (rs80359187) is reported in the literature in multiple individuals with a personal and/or family history of breast, ovarian, and/or pancreatic cancer (Alemar 2017, Hahn 2003, Ikeda 2001, Li 2018). In one family, this variant segregated with disease in at least three affected family members (Hahn 2003). This variant is found on a single chromosome in the Genome Aggregation Database (1/250980 alleles), indicating it is not a common polymorphism. The glycine at codon 3076 is highly conserved, and functional analyses indicate decreased activity in assays of homology-directed recombination (HDR) (Guidugli 2013, Guidugli 2018). Additionally, other amino acid substitutions at this codon (p.Gly3076Arg, p.Gly3076Val) exhibit decreased HDR activity (Guidugli 2018), and p.Gly3076Val has been reported in a cohort of individuals with breast and/or ovarian cancer (Alemar 2017); however, the clinical significance of other variants at the same codon has not been conclusively determined. Still, based on available information, the p.Gly3076Glu variant is considered to be likely pathogenic. References: Alemar B et al.
