Invitae RCV001218310 SCV001390185 uncertain significance Familial cancer of breast 2019-05-02 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with CHEK2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces leucine with proline at codon 499 of the CHEK2 protein (p.Leu499Pro). The leucine residue is highly conserved and there is a moderate physicochemical difference between leucine and proline. 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.
