It has been classified as a Variant of Uncertain Significance. 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: "Tolerated"; PolyPhen-2: "Possibly 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 leucine with proline at codon 1854 of the CACNA1C protein (p.Leu1854Pro). The leucine residue is moderately conserved and there is a moderate physicochemical difference between leucine and proline. |
