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]

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -

The p.Ala2951Thr variant has been reported in our laboratory as well as in the literature in 36/5864 (0.006 frequency) proband chromosomes and in 1/1018 control chromosomes (0.001 frequency) (Bergthorsson_2001_11389159, Borg_2010_20104584, Saxena_2006_17018160, Lin_2003_12815053, Spitzer_2000_10699917, Serova-Sinilnikova_1997_9150172, Weber_2006_16685647, Wagner_1999_9971877, Waddell_2008_18497862). It is listed in dbSNP database (ID#:rs11571769) but no frequency information was provided, and so the prevalence of this variant in the general population is not known. The p.Ala2951 residue is conserved across vertebrate species, and computational analyses (PolyPhen2, SIFT, AlignGVGD) suggest that the p.Ala2951Thr variant may impact the protein. However, this information is not predictive enough to assume pathogenicity. In one study, this variant did not co-segregate with cancer in three families, and its frequency in 4680 clinical samples was similar to that of the control population (Deffenbaugh_2002_12215251). Notably, this variant has been identified in the UMD database in a total of 15 individuals who had a second pathogenic variant (9 with BRCA2 mutations and 6 with BRCA1) and associated with a breast or ovarian cancer phenotype, increasing the likelihood that the p.Ala2951Thr variant does not have clinical significance. In addition, Myriad calls this variant as a polymorphism. In summary, based on the above information this variant is classified as benign. -
