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]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

In the published literature, this variant has been reported in individuals with breast and/or ovarian cancer (PMIDs: 23683081 (2013), 16758124 (2006), 15937982 (2005)). Additionally, the variant has been characterized as being a variant of uncertain significance in a multifactorial likelihood study (PMID: 31131967 (2019)). The frequency of this variant in the general population, 0.000046 (1/21644 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant. -

Variant summary: BRCA2 c.5882G>A (p.Ser1961Asn) results in a conservative amino acid change located in the BRCA2 repeat region, between the repeats BRC6 and BRC7 (IPR002093) of the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 8e-06 in 250986 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.5882G>A has been reported in the literature in individuals affected with Hereditary Breast and Ovarian Cancer (Blay_2013, Infante_2006, Velasco_2005). 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 (BRCA1 c.3331_3334delCAAG, p.Gln1111fsX5 in the BIC database), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Nine submitters have cited clinical-significance assessments for this variant to ClinVar after 2014 and classified as benign/likely benign (n=6) and VUS (n=3). Based on the evidence outlined above, the variant was classified as VUS-possibly benign. -
