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]

The BRCA2 p.Gly715= variant was identified in 1 of 820 proband chromosomes (frequency: 0.001) from individuals or families with breast cancer (Fackenthal 2012). The variant was also identified in dbSNP (ID: rs112566179) as "With other allele", ClinVar (classified as benign by Invitae, GeneDx, Color and ENIGMA; as likely benign by three submitters), LOVD 3.0 (3x), and in UMD-LSDB (4x as unclassified variant). The variant was identified in UMD-LSDB with a co-occurring pathogenic BRCA2 variant (c.6159delT, p.Ala2054Leufs*16), increasing the likelihood that the p.Gly715= variant does not have clinical significance. The variant was identified in control databases in 43 of 277062 chromosomes at a frequency of 0.0002 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 42 of 24028 chromosomes (freq: 0.002) and Latino in 1 of 34366 chromosomes (freq: 0.00003), while the variant was not observed in the Other, European, Ashkenazi Jewish, East Asian, Finnish, or South Asian populations. The p.Gly715= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. In addition, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information, the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
