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.3916G>A (p.Val1306Ile) 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 allele was found at a frequency of 1.9e-05 in 209536 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.3916G>A has been reported in the literature in individuals undergoing testing for hereditary breast and/or ovarian cancer but has been classified as unequivocally neutral based on multifactorial probability models that employed several key parameters, namely co-occurrence in trans of a VUS with known deleterious mutations; detailed analysis, by logistic regression, of personal and family history of cancer in VUS-carrying probands; and, in a subset of probands, an analysis of cosegregation with disease in pedigrees (example, Easton_2007, Lindor_2012). These report(s) do not provide unequivocal conclusions about association of the variant with Hereditary Breast And Ovarian Cancer Syndrome. No experimental evidence demonstrating an impact on protein function were ascertained within the context of this evaluation, although this variant has been included among the neutrality controls in validation panels reviewing functional assays for analysis of VUS in BRCA2 (example Guidugli_2012). Multiple clinical diagnostic laboratories and an expert panel (ENIGMA) have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Multiple laboratories reported the variant with conflicting assessments but a predominant consensus as benign (to include the expert panel)/likely benign (n=6). Based on the evidence outlined above, the variant was classified as benign. -

The BRCA2 c.3916G>A (p.Val1306Ile) missense change has a maximum subpopulation frequency of 0.0041% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/variant/13-32912408-G-A). Six of seven in silico tools predict a benign effect of this variant on protein function (BP4), but to our knowledge these predictions have not been confirmed by functional assays. This variant has been reported in two women older than 70 years of age who have never had cancer (BS2_supporting; https://whi.color.com/variant/13-32907401-G-C). It has also been reported in an individual with breast cancer (PMID: 20104584). In summary, this variant meets criteria to be classified as likely benign based on the ACMG/AMP criteria: BS2_supporting, BP4. -

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as 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. -
