Invitae RCV002514078 SCV001377981 uncertain significance Catecholaminergic polymorphic ventricular tachycardia 1 2019-06-29 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 (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 been observed in an individual affected with long QT syndrome (PMID: 26132555). ClinVar contains an entry for this variant (Variation ID: 207952). This variant is not present in population databases (ExAC no frequency). This sequence change replaces arginine with tryptophan at codon 3673 of the RYR2 protein (p.Arg3673Trp). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and tryptophan.
