Description

This sequence change replaces isoleucine with leucine at codon 4197 of the RYR2 protein (p.Ile4197Leu). The isoleucine residue is highly conserved and there is a small physicochemical difference between isoleucine and leucine. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. 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: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has been observed to be de novo in an individual with clinical features of catecholaminergic polymorphic ventricular tachycardia (CPVT) (Invitae). This variant is not present in population databases (ExAC no frequency).
