Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP4_StrongBP6

The NM_000059.4(BRCA2):​c.8090G>A​(p.Ser2697Asn) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000186 in 1,614,034 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S2697R) has been classified as Likely benign.

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.8090G>A (p.Ser2697Asn) results in a conservative amino acid change in the encoded protein sequence. Four of four in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 4e-05 in 251314 control chromosomes. This frequency is not significantly higher than expected for a pathogenic variant in BRCA2 causing Hereditary Breast And Ovarian Cancer Syndrome (4e-05 vs 0.00075), allowing no conclusion about variant significance. c.8090G>A has been reported in the literature in individuals affected with Hereditary Breast And Ovarian Cancer Syndrome. These reports do not provide unequivocal conclusions about association of the variant with Hereditary Breast And Ovarian Cancer Syndrome. Co-occurrences with one pathogenic variant have been reported in multiple individuals (BRCA2 c.1800T>G, p.Tyr600Ter, BIC and UMD databases; BRCA1, c.2138C>G, p.Ser713Ter, internal database), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Ten clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Multiple laboratories reported the variant with conflicting assessments (benign/likely benign n=7, VUS n=3). Based on the evidence outlined above, the variant was classified as benign. -

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

BS1, BS3, BP5_Strong c.8090G>A, located in exon 18 of the BRCA2 gene, is predicted to result in the substitution of Ser by Asn at codon 2697, p.(Ser2697Asn). It was found in 5/17684 alleles,with a filter allele frequency of 0.011% at 95% confidence, within the East Asian population in the gnomAD v2.1 (non-cancer, exome only subset) (BS1). This position is located in a (potentially) clinically important functional domain. SpliceAI algorithm predicts no significant impact on splicing but the Bayesdel no-AF meta-predictor score for this variant (0.258) suggests an intermediate effect on the protein function. This variant has been reported by calibrated studies to affect protein function similar to benign control variants (PMIDs: 33609447, 32444794, 29884841) (BS3). Published clinical data for a multifactorial likelihood analysis (PMID: 31131967) showed a combined LR=0,046 (BP5_Strong). This variant has been reported in ClinVar (6x benign, 9x likely benign, 4x uncertain significance) and LOVD (4x likely benign, 5x uncertain significance) databases, and in BRCA Exchange database as not yet reviewed. Based on currently available information, the variant c.8090G>A should be considered a benign variant. -
