Genes affected
BRCA2 (HGNC:1101): (BRCA2 DNA repair associated) Inherited mutations in BRCA1 and this gene, BRCA2, confer increased lifetime risk of developing breast or ovarian cancer. Both BRCA1 and BRCA2 are involved in maintenance of genome stability, specifically the homologous recombination pathway for double-strand DNA repair. The largest exon in both genes is exon 11, which harbors the most important and frequent mutations in breast cancer patients. The BRCA2 gene was found on chromosome 13q12.3 in human. The BRCA2 protein contains several copies of a 70 aa motif called the BRC motif, and these motifs mediate binding to the RAD51 recombinase which functions in DNA repair. BRCA2 is considered a tumor suppressor gene, as tumors with BRCA2 mutations generally exhibit loss of heterozygosity (LOH) of the wild-type allele. [provided by RefSeq, May 2020]

Variant summary: BRCA2 c.1181A>C (p.Glu394Ala) results in a non-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 allele was found at a frequency of 2.4e-05 in 250208 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.1181A>C has been reported in the literature in individuals affected with Hereditary Breast and Ovarian Cancer (Caux-Moncoutier_2011, Palomba_2009, Carney_2010, Miolo_2009, Apessos_2018, Lebo_2018). These reports however, do not provide unequivocal conclusions about association of the variant with Hereditary Breast and Ovarian Cancer. A co-occurrence with another pathogenic BRCA2 variant, c.8168A>G (p.Asp2723Gly) has been reported (NHGRI-BIC database), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 21120943, 19619314, 21218378, 19818148, 29310832, 28726806) ClinVar contains an entry for this variant (Variation ID: 51077). Based on the evidence outlined above, the variant was classified as VUS-possibly benign. -

Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

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. -
