Department of Pathology and Laboratory Medicine, Sinai Health System	RCV000173627	SCV000591742	benign	not specified		no assertion criteria provided	clinical testing	The BRCA2 p.Val465Val variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. In addition, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict the abolishment of an existing splice site or the creation of a new splice site, and a splicing minigene assay found the variant did not have an effect on splicing (Théry 2011). The variant was identified in the literature in 2 of 8048 proband chromosomes from individuals or families with breast or ovarian cancer; however control chromosomes were not evaluated in this study thus the prevalence of the variant in the general population could not be determined (van der Hout 2006). Another variant with the same synonymous amino acid change but a different nucleotide change (c.1395A>T) was identified in one individual with breast cancer in a study by Evans (2008); however, control chromosomes were not included in this study. The p.Val465Val variant was identified in the NIH Polymorphism Discovery Resource (NIHPDR) PDR90 cohort in 1 of 180 chromosomes (frequency: 0.006), and in the Exome Variant Server Exome Sequencing Project in 4 of 13006 European American alleles (frequency 0.0003), increasing the likelihood that this may be a low frequency benign variant in certain populations of origin. The variant was also identified in dbSNP (ID: rs11571641) “With uncertain allele”, HGMD, LOVD, the ClinVar database (classified as benign by Invitae and GeneDx), the BIC database (1X with unknown clinical importance), and UMD (25X as a neutral variant). In UMD the variant was identified with three different co-occurring pathogenic BRCA2 variants and one pathogenic BRCA1 variant, increasing the likelihood that the p.Val465Val variant does not have clinical significance. Furthermore, Myriad classifies this as a polymorphism (personal communication). In summary, based on the above information, this variant meets our laboratory's criteria to be classified as benign.
