Labcorp Genetics (formerly Invitae), Labcorp RCV000471632 SCV000553032 uncertain significance Long QT syndrome 2016-04-07 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a CACNA1C-related disease. This sequence change replaces aspartic acid with glycine at codon 446 of the CACNA1C protein (p.Asp446Gly). The aspartic acid residue is highly conserved and there is a moderate physicochemical difference between aspartic acid and glycine. 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.
