MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Voltage-gated sodium channels are transmembrane glycoprotein complexes composed of a large alpha subunit with 24 transmembrane domains and one or more regulatory beta subunits. They are responsible for the generation and propagation of action potentials in neurons and muscle. This gene encodes one member of the sodium channel alpha subunit gene family. It is expressed in skeletal muscle, and mutations in this gene have been linked to several myotonia and periodic paralysis disorders. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice heterozygous or homozygous for a knock-in allele develop myotonia, increased myofiber damage, K+-sensitive paralysis and susceptibility to delayed weakness during recovery from fatigue. Homozygotes show perinatal lethality, low survival rate, unusual hind-limb clasping and reduced body weight. [provided by MGI curators]
