RCV000538822 | SCV000653649 | uncertain significance | Hypokalemic periodic paralysis, type 1; Malignant hyperthermia, susceptibility to, 5 | 2021-08-30 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine with histidine at codon 594 of the CACNA1S protein (p.Arg594His). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and histidine. This variant is present in population databases (rs762032797, ExAC 0.01%). This variant has not been reported in the literature in individuals affected with CACNA1S-related conditions. ClinVar contains an entry for this variant (Variation ID: 473967). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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. |
