ClinVar

Description

The BRCA2 p.Val3240Val 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, and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. The variant was not identified in the literature, but was identified in the BIC database (5X as a variant with unknown clinical importance), and in dbSNP (ID: rs80359810) “With untested allele”. The variant was identified in the NHLBI Exome Sequencing Project (Exome Variant Server) in 10 of 4406 African American chromosomes (frequency: 0.002), increasing the likelihood that this may be a low frequency benign variant in certain populations of origin. 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.
