MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is the beta 2 subunit of the type II voltage-gated sodium channel. The encoded protein is involved in cell-cell adhesion and cell migration. Defects in this gene can be a cause of Brugada Syndrome, atrial fibrillation, or sudden infant death syndrome. [provided by RefSeq, Jul 2015]
PHENOTYPE: Mice homozygous for a knock-out allele display decreased sodium channel density, altered voltage dependence of inactivation, and increased susceptibility to pilocarpine-induced seizures but appear normal in other neurological tests. Impaired glucose tolerance in homozygous mutant males is seen. [provided by MGI curators]
