Description

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: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with RYR2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces lysine with threonine at codon 439 of the RYR2 protein (p.Lys439Thr). The lysine residue is highly conserved and there is a moderate physicochemical difference between lysine and threonine.
