SCN8A sodium voltage-gated channel alpha subunit 8

Gene ID: 6334, updated on 3-Nov-2024
Gene type: protein coding
Also known as: MED; PN4; CIAT; BFIS5; DEE13; NaCh6; CERIII; EIEE13; MYOCL2; Nav1.6

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.[provided by RefSeq, May 2010]
