Gene Gene information from NCBI Gene database.
Entrez ID 6334
Gene name Sodium voltage-gated channel alpha subunit 8
Gene symbol SCN8A
Synonyms (NCBI Gene)
BFIS5CERIIICIATDEE13EIEE13MEDMYOCL2NaCh6Nav1.6PN4
Chromosome 12
Chromosome location 12q13.13
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
