Invitae RCV001913694 SCV002185484 uncertain significance Andersen Tawil syndrome; Short QT syndrome type 3 2021-06-14 criteria provided, single submitter clinical testing 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with KCNJ2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with arginine at codon 33 of the KCNJ2 protein (p.Gly33Arg). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and arginine.
