The BRCA2 c.3453C>G (p.I1151M) variant has been reported in heterozygosity in at least three individuals with breast and/or ovarian cancer and one individual with prostate cancer (PMID: 27878467, 27062684, 33471991, 21952622). It has also been reported as homozygous in the Breast cancer Information Core (PMID: 10923033). It was not observed in the large and broad cohorts of the Genome Aggregation Database (http://gnomad.broadinstitute.org). The variant has been reported in ClinVar (Variation ID 37842). Functional studies have not been performed, and in silico predictions of the variant's effect on protein function are inconclusive. The evidence is insufficient to meet ACMG/AMP criteria for classifying the variant as benign or pathogenic. Thus, the clinical significance of this variant is currently uncertain. (less)

Variant summary: BRCA2 c.3453C>G (p.Ile1151Met) results in a conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant was absent in 250978 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance.c.3453C>G has been reported in the literature in at least one individual affected with prostate cancer (Kote-Jarai_2011), one individual affected with breast cancer and/or ovarian cancer (Azzollini_2016), and one individual who was previously tested negative for BRCA 1/2 mutation and retested using multigene panels (Yadav_2017), and in one female without cancer, but potentially before age-of-onset (Dong_2021). These report(s) do not provide unequivocal conclusions about association of the variant with Hereditary Breast And Ovarian Cancer Syndrome. Co-occurrences with another pathogenic variant have been reported (BRCA2 c.4470dupA, p.Leu1491Thr fs*23), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Seven clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Multiple laboratories classified the variant as VUS (n=3) or likely benign (n=4). Based on the evidence outlined above, the variant was classified as uncertain significance - possibly benign. (less)

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
