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]

This variant has not been reported in the literature in individuals affected with CACNA1S-related conditions. 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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant is present in population databases (no rsID available, gnomAD 0.002%). This variant, c.5595_5600del, is a complex sequence change that results in the deletion of 3 and insertion of 1 amino acid(s) in the CACNA1S protein (p.Gln1865_Thr1867delinsHis). -
