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

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). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

The p.Ala487Glu variant was identified in 4 of 5096 proband chromosomes (frequency: 0.001) from individuals with breast or ovarian cancer (Borg 2010, Lindor 2012, Soegaard 2008); however, control chromosomes were not evaluated in these studies, thus the prevalence of this variant in the general population could not be determined. The variant was also identified in dbSNP (ID: rs56390402), the ClinVar database (classified as a benign variant by Ambry Genetics and the Sharing Clinical Reports Project (derived from Myriad reports); classified as likely benign by GeneDx), the BIC database (21X with unknown clinical importance), and UMD (6X as an unclassified variant). In UMD the variant was identified in one sample with a co-occurring pathogenic BRCA2 variant (c.6816_6820delAAGAG (p.Gly2274AlafsX17)), and in another sample with a co-occurring pathogenic BRCA1 variant (c.4327C>T (p.Arg1443X)), increasing the likelihood that the p.Ala487Glu variant does not have clinical significance. The variant was listed in the Exome Aggregation Consortium (ExAC) database (released Oct 20th, 2014) in 6 of 66248 chromosomes (frequency: 0.00009) from a population of European (Non-Finnish) individuals, and was also found in 1 of 8598 European American chromosomes in the Exome Variant Server ESP project. This low number of observations and low frequency is not substantive enough to determine the prevalence of the variant in the general population and its relationship to disease. The variant occurs outside of the splicing consensus sequence and one of five in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predicts a difference in splicing, but this information is not very predictive of pathogenicity. The p.Ala487 residue is not conserved in mammals and other organisms, and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of 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 predicted benign. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

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. -
