Invitae RCV000466045 SCV000549569 uncertain significance Hereditary breast and ovarian cancer syndrome 2017-01-19 criteria provided, single submitter clinical testing This sequence change replaces phenylalanine with cysteine at codon 1559 of the BRCA2 protein (p.Phe1559Cys). The phenylalanine residue is weakly conserved and there is a large physicochemical difference between phenylalanine and cysteine. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a BRCA2-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies. In summary, this variant is a novel missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance.
