Invitae RCV001049462 SCV001213511 uncertain significance Hypokalemic periodic paralysis, type 1; Malignant hyperthermia, susceptibility to, 5 2019-05-12 criteria provided, single submitter clinical testing This sequence change replaces histidine with arginine at codon 1768 of the CACNA1S protein (p.His1768Arg). The histidine residue is weakly conserved and there is a small physicochemical difference between histidine and arginine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with CACNA1S-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The arginine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
