SCN8A - sodium voltage-gated channel alpha subunit 8 Gene
Also Known as MED; PN4; CIAT; BFIS5; DEE13; NaCh6; CERIII; EIEE13; MYOCL2; Nav1.6
Species: Homo sapiens
About SCN8A
This gene has 19 transcripts (splice variants), 276 orthologues, 26 paralogues and is associated with 8 phenotypes. Biased expression in brain (RPKM 8.0), testis (RPKM 1.0) and 2 other tissues.
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]
