Invitae RCV000228648 SCV000289757 uncertain significance Hereditary breast and ovarian cancer syndrome 2019-12-30 criteria provided, single submitter clinical testing This sequence change replaces lysine with arginine at codon 701 of the BRCA1 protein (p.Lys701Arg). The lysine residue is moderately conserved and there is a small physicochemical difference between lysine and arginine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with BRCA1-related disease. ClinVar contains an entry for this variant (Variation ID: 229967). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The arginine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
