Description

 Calcium channel, voltage-dependent, L type, alpha 1S subunit (HGNC Symbol)

Entrez gene summary

 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]
