Sodium channel, voltage-gated, type IX, alpha subunit

PN1, Nav1.7, Gdn, SCN9A, SERPINE2
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.
