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]

Review Status: no assertion criteria provided
Collection Method: clinical testing

The BRCA2 c.5879G>A variant is predicted to result in the amino acid substitution p.Cys1960Tyr. This variant has been reported as a variant of uncertain significance in two apparently unrelated individuals with breast cancer (Borg et al. 2010. PubMed ID: 20104584; Fackenthal et al. 2012. PubMed ID: 22034289). This variant was also reported as probably benign in a patient with osteosarcoma (Zhang et al. 2015. PubMed ID: 26580448). This variant is reported in 0.16% of alleles in individuals of African descent in gnomAD. In ClinVar, this variant has been interpreted by the majority of submitters as benign/likely benign (https://www.ncbi.nlm.nih.gov/clinvar/variation/38003/). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

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

Variant summary: The BRCA2 c.5879G>A (p.Cys1960Tyr) variant involves the alteration of a non-conserved nucleotide. The variant is located outside of any know functional domain or repeat and 3/5 in silico tools predict a benign outcome for this variant. This variant was found in 17/120980 control chromosomes of ExAC, predominantly observed in the African subpopulation at a frequency of 0.001587 (16/10082). This frequency is about 2 times the estimated maximal expected allele frequency of a pathogenic BRCA2 variant (0.0007503), suggesting this is likely a benign polymorphism found primarily in the populations of African origin. The variant is present in a control population dataset of gnomAD at a frequency of 0.0001372 (38/277020 chrs), mainly in individuals of African origin: 0.0015 (36/24015 chrs, including 7 homozygotes). This data support the speculation that the variant of interest may be an ethnic-specific functional polymorphism. The variant has been reported in affected individuals via publications with limited information (no co-occurrence or co-segregation information provided). In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as benign/likely benign. Furthermore, ClinVar - SCRP (RCV000031584.4) cites the variant to co-occur with pathogenic BRCA1 variants, 3555del4 and IVS23+1G>A. In addition, the variant was identified to co-occure with a known pathogenic variant in BRCA1 c.4357+1G>A/IVS12+1G>T, further supporting the non-pathogenic role of c.58769G>A variant. Taken together, this variant is classified as benign. -
