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 allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.

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.

Department of Pathology and Laboratory Medicine,Sinai Health System	RCV001353780	SCV000591765	benign	Malignant tumor of breast		no assertion criteria provided	clinical testing	The BRCA2 p.Asp596His variant was identified in 7 of 7970 proband chromosomes (frequency: 0.001) from individuals or families with ovarian and breast cancer (Borg 2010, Brozek 2007, Lee 2008, Machado 2007, Pal 2005); however, an insufficient number of controls were included in these studies to determine the frequency of this variant in the general population. The variant was also identified by our laboratory in 2 individuals with breast cancer. The variant was identified by the Exome Variant Server project in 5 of 12995 European American/African American alleles (frequency: 0.0004), although 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 p.Asp596 residue is conserved across most mammals, but not across lower organisms. 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. An in silico analysis study by Lee (2008) classified this variant as low-frequency unclassified variant with medium to high risk in selected computational predictive programs; however, a population study by Pal (2005) noted that a tumour with the variant had low malignant potential. This variant was identified in dbSNP (ID: rs56328701) “With untested allele”, HGMD, ClinVar database, the BIC database (50X with no clinical importance), and UMD (44X as a neutral variant). In UMD the c.1786G>C variant was identified with five different co-occurring pathogenic BRCA1 and BRCA2 variants, increasing the likelihood that the p.Asp596His variant does not have clinical significance. In addition, the variant was classified as a benign by the Sharing Clinical Reports Project (SCRP) (submitted within the ClinVar database and derived from Myriad reports). In summary, based on the above information, this variant meets our laboratory's criteria to be classified as benign.
