Invitae RCV002523276 SCV000541702 uncertain significance Catecholaminergic polymorphic ventricular tachycardia 1 2016-11-26 criteria provided, single submitter clinical testing This variant does not occur within one of the three regions of the RYR2 gene (N-terminal domain, central domain, or channel region) where other pathogenic variants have been reported to cluster (PMID: 19926015). In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. 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. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a RYR2-related disease. This sequence change replaces leucine with serine at codon 1459 of the RYR2 protein (p.Leu1459Ser). The leucine residue is highly conserved and there is a large physicochemical difference between leucine and serine.
