Genes affected
CACNA1S (HGNC:1397): (calcium voltage-gated channel subunit alpha1 S) This gene encodes one of the five subunits of the slowly inactivating L-type voltage-dependent calcium channel in skeletal muscle cells. Mutations in this gene have been associated with hypokalemic periodic paralysis, thyrotoxic periodic paralysis and malignant hyperthermia susceptibility. [provided by RefSeq, Jul 2008]

Malignant hyperthermia of anesthesia Uncertain:1
Uncertain significance, criteria provided, single submitter | research | CSER _CC_NCGL, University of Washington | Oct 01, 2016 | Found in patient having exome sequencing for an unrelated indication. No known history of malignant hyperthermia. This interpretation considers GERP score and allele frequency data, in addition to published reports of the variant in the literature, available at the time of review. - |
