Invitae	RCV001243195	SCV001416335	uncertain significance	Long QT syndrome	2019-08-27	criteria provided, single submitter	clinical testing	This sequence change replaces arginine with histidine at codon 1123 of the CACNA1C protein (p.Arg1123His). The arginine residue is moderately conserved and there is a small physicochemical difference between arginine and histidine. This variant is present in population databases (rs745853358, ExAC 0.02%). This variant has not been reported in the literature in individuals with CACNA1C-related conditions. ClinVar contains an entry for this variant (Variation ID: 308144). 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: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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.
