Chr: 6 Mapping Details/Browsers

Description

Predicted to have voltage-gated sodium channel activity. Predicted to be involved in membrane depolarization during action potential; neuronal action potential; and sodium ion transmembrane transport. Predicted to localize to axon and voltage-gated sodium channel complex. Human ortholog(s) of this gene implicated in benign familial neonatal epilepsy and early infantile epileptic encephalopathy 13. Is expressed in heart and nervous system. Orthologous to human SCN8A (sodium voltage-gated channel alpha subunit 8).
