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]

This missense variant replaces histidine with arginine at codon 114 of the BRCA2 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with breast cancer (PMID: 19491284) and in a breast cancer case-control meta-analysis in 5/60463 cases and 4/53461 unaffected individuals (PMID: 33471991; Leiden Open Variation Database DB-ID BRCA2_001948). A multifactorial analysis also has reported co-occurrence and family history likelihood ratios for pathogenicity of 1.0498 and 0.5618, respectively (PMID: 31131967). This variant has been identified in 27/251014 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The BRCA2 c.341A>G (p.His114Arg) variant has been reported in the published literature in breast cancer cases (PMIDs: 33471991 (2021), 37060015 (2023)), including early-onset (PMID: 19491284 (2009)), as well as reportedly healthy individuals (PMID: 33471991 (2021)). The frequency of this variant in the general population, 0.00054 (14/25950 chromosomes in Swedish subpopulation (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is higher than would generally be expected for pathogenic variants in this gene. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant is denoted BRCA2 c.341A>G at the cDNA level, p.His114Arg (H114R) at the protein level, and results in the change of a Histidine to an Arginine (CAT>CGT). Using alternate nomenclature, this variant would be defined as BRCA2 569A>G. This variant was observed in at least one woman with early onset breast cancer (Haffty 2009). BRCA2 His114Arg was observed at an allele frequency of 0.04% (8/22,204) in individuals of Finnish ancestry in large population cohorts (Lek 2016). This variant is not located in a known functional domain. In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function. Based on currently available evidence, it is unclear whether BRCA2 His114Arg is a pathogenic or benign variant. We consider it to be a variant of uncertain significance. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This missense variant replaces histidine with arginine at codon 114 of the BRCA2 protein. Computational prediction suggests that this variant may not impact protein structure and function. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in two individuals affected with breast cancer (PMID: 19491284, 37060015), and it has been detected in a breast cancer case-control meta-analysis in 5/60466 cases and 4/53461 unaffected individuals (PMID: 33471991; Leiden Open Variation Database DB-ID BRCA2_001948). Multifactorial analyses have reported likelihood ratios (LRs) reaching a combined LR = 0.5302 based on personal and family history for 4 carriers and co-occurrence with a pathogenic variant (PMID: 31131967, 31853058). This variant has been identified in 27/251014 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

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. -
