Invitae RCV001218682 SCV001390577 likely pathogenic Hypokalemic periodic paralysis, type 1; Malignant hyperthermia, susceptibility to, 5 2023-05-22 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. ClinVar contains an entry for this variant (Variation ID: 402472). This sequence change affects a donor splice site in intron 13 of the CACNA1S gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in CACNA1S are known to be pathogenic (PMID: 26247046, 28012042). This variant is present in population databases (rs745712829, gnomAD 0.009%). This variant has not been reported in the literature in individuals affected with CACNA1S-related conditions.
