Invitae RCV000798318 SCV000937927 uncertain significance Familial cancer of breast 2019-08-14 criteria provided, single submitter clinical testing This sequence change replaces serine with arginine at codon 120 of the CHEK2 protein (p.Ser120Arg). The serine residue is moderately conserved and there is a moderate physicochemical difference between serine and arginine. 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. 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. This variant has not been reported in the literature in individuals with CHEK2-related disease. This variant is not present in population databases (ExAC no frequency).
