Invitae | RCV002562471 | SCV001390998 | uncertain significance | Catecholaminergic polymorphic ventricular tachycardia 1 | 2019-08-09 | 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 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 been observed in an individual affected with clinical features of catecholaminergic polymorphic ventricular tachycardia (Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change replaces leucine with valine at codon 459 of the RYR2 protein (p.Leu459Val). The leucine residue is highly conserved and there is a small physicochemical difference between leucine and valine. |
