Gene: SCN9A (sodium voltage-gated channel alpha subunit 9) Homo sapiens
Symbol: SCN9A
Name: sodium voltage-gated channel alpha subunit 9
Description: This gene encodes a voltage-gated sodium channel which plays a significant role in nociception signaling. Mutations in this gene have been associated with primary erythermalgia, channelopathy-associated insensitivity to pain, and paroxysmal extreme pain disorder. [provided by RefSeq, Aug 2009]
Type: protein-coding
RefSeq Status: REVIEWED
