Invitae RCV002523274 SCV000541695 uncertain significance Catecholaminergic polymorphic ventricular tachycardia 1 2016-12-29 criteria provided, single submitter clinical testing This sequence change replaces arginine with lysine at codon 3381 of the RYR2 protein (p.Arg3381Lys). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and lysine. It also falls at the last nucleotide of exon 69 of the RYR2 coding sequence. 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 sequence changes on RNA splicing suggest that this variant may alter RNA splicing, but this prediction has not been confirmed by published transcriptional studies. 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.
