Labcorp Genetics (formerly Invitae), Labcorp RCV002806462 SCV003196660 pathogenic Hypokalemic periodic paralysis, type 1; Malignant hyperthermia, susceptibility to, 5 2023-01-22 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with CACNA1S-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Trp265*) in the CACNA1S gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CACNA1S are known to be pathogenic (PMID: 26247046, 28012042).
