Gene: SCN8A
Alternate names for this Gene: BFIS5|CERIII|CIAT|DEE13|EIEE13|MED|MYOCL2|NaCh6|Nav1.6|PN4
Gene Summary: 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 cognitive disability, pancerebellar atrophy and ataxia. Alternate splicing results in multiple transcript variants.
Gene is located in Chromosome: 12
Location in Chromosome : 12q13.13
Description of this Gene: sodium voltage-gated channel alpha subunit 8
Type of Gene: protein-coding
