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]

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.Tyr1894Tyr variant in BRCA2 is classified as likely benign/benign because it does not alter an amino acid residue, is not located within the splice consensus site, and computational splice prediction tools do not predict an impact on splicing. It has been identified in 2/30522 of South Asian chromosomes by gnomAD (http://gnomad.broadinstitute.org). This variant was classified as Likely Benign on June 29, 2017 by the ClinGen-approved ENIGMA expert panel (Variation ID 135806). ACMG/AMP Criteria applied: BP4, BP7. -

Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as likely 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. -
