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.7102T>G (p.Leu2368Val) results in a conservative amino acid change in 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 7.8e-05 in 282366 control chromosomes, exclusively found within the East Asian subpopulation with a frequency of 0.0011 in the gnomAD database. The observed variant frequency within East Asian control individuals in the gnomAD database is approximately 1.5 fold of the estimated maximal expected allele frequency for a pathogenic variant in BRCA2 causing Hereditary Breast and Ovarian Cancer phenotype (0.00075), strongly suggesting that the variant is a benign polymorphism found primarily in populations of East Asian origin. The variant, c.7102T>G, has been reported in the literature in individuals affected with breast cancer, but without evidence for causality (Carney_2010, Chan_2018). In addition, co-occurrences with another pathogenic BRCA2 variant have been reported (BRCA2 c.7878G>A (p.Trp2626X); in Carney_2010 and in our internal database), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Four other clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, and classified the variant a VUS (1x), Likely benign (2x) and Benign (1x). Based on the evidence outlined above, the variant was classified as benign. -

Significance:Likely benign
Review Status:no assertion criteria provided
Collection Method:clinical testing

The BRCA2 p.Leu2368Val variant was identified in the literature in an individual with breast cancer (Carney 2010). The variant was identified in co-occurrence with a pathogenic BRCA2 variant (p.Trp2626X) in this individual, increasing the likelihood that the p.Leu2368Val variant may not have clinical significance. The variant was also identified in dbSNP (ID: rs397507382) “With Likely Benign allele”, and in the Clinvar database (classified as a benign variant by the Sharing Clinical Reports Project (SCRP) (derived from Myriad reports); classified as likely benign by Ambry Genetics). The variant occurs outside of the splicing consensus sequence and five in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. The p.Leu2368 residue is not conserved in mammals and the variant amino acid valine (Val) is present in rat, increasing the likelihood that this variant does not have clinical significance. Computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. 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. -
