Therefore, it has been classified as a Variant of Uncertain Significance. This variant disrupts the p.Asn2386 amino acid residue in RYR2. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 12106942, 22828895, 15364613). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but 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 RYR2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces asparagine with lysine at codon 2386 of the RYR2 protein (p.Asn2386Lys). The asparagine residue is highly conserved and there is a moderate physicochemical difference between asparagine and lysine.
