MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the sodium channel alpha subunit gene family. The encoded protein forms the ion pore region of the voltage-gated sodium channel. This protein is essential for the rapid membrane depolarization that occurs during the formation of the action potential in excitable neurons. Mutations in this gene are associated with mental retardation, pancerebellar atrophy and ataxia. Alternate splicing results in multiple transcript variants.[provided by RefSeq, May 2010]
PHENOTYPE: Spontaneous mutant homozygotes have ataxia, dystonia, muscular atrophy, progressive paralysis, Purkinje cell loss, in some cases severe head-tossing and for severe alleles, juvenile lethality. A mild, semidominant ENU allele causes deafness of variable penetrance and severity and mild tremor. [provided by MGI curators]
