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]

Collection Method: clinical testing

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. -

Significance: Benign

Review Status: no assertion criteria provided

Collection Method: clinical testing

The p.Met784Val variant has been reported in the literature in 160/11460 proband chromosomes of individuals with HBOC and sporadic breast cancer. It was also found in 35/5936 control chromosomes tested, increasing the likelihood this variant does not have clinical significance (Spearman 2008, Wagner 1999, Capanu 2011, Freedman_2004, Ishitobi_2003, Johnston_2012, Krupa_2009, Seo_2004, Han_2006). The variant has also been reported in the UMD (x1), LOVD (x2), BIC (x47), and BOCs databases. It is listed in the dbSNP database as coming from a "clinical source" (ID#: rs11571653) with a MAF score of 0.007 (1000 Genomes). Of particular interest are the findings that this variant is considered a polymorphism in the Japanese population, and that of the 168 chromosomes tested in the HapMap Japanese cohort, the variant was found in almost 20 chromosomes (allele frequency of 0.107). The p.Met784 residue is not conserved in mammals, and the variant amino acid Valine (Val) is present in the dog, rat and opossum at this position, increasing the likelihood that an alteration to this residue may not have functional significance. The identification of this variant in the presence of a second pathogenic variant increases the likelihood that this variant does not have clinical significance. In summary, based on the above information, this variant is classified as Benign. -
