Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 8.1e-06 in 246060 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. The variant, c.7916C>T, has been reported in the literature in individuals affected with Hereditary Breast and Ovarian Cancer (Deihimi_2017, Jakimovska_2018, Schenkel_2016). These report(s) do not provide unequivocal conclusions about association of the variant with Hereditary Breast and Ovarian Cancer. Co-occurrences with other pathogenic variant(s) have been reported (BRCA2 c.5645C>A, p.Ser1882X), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Two ClinVar submissions from clinical diagnostic laboratories (evaluation after 2014) cite the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as VUS-possibly benign.
