Summary: Enables voltage-gated sodium channel activity. Involved in behavioral response to pain; circadian rhythm; and detection of stimulus involved in sensory perception. Acts upstream of or within several processes, including cardiac conduction; regulation of atrial cardiac muscle cell membrane depolarization; and sodium ion transport. Located in C-fiber and plasma membrane. Is expressed in brain; ganglia; and heart. Human ortholog(s) of this gene implicated in familial episodic pain syndrome 2. Orthologous to human SCN10A (sodium voltage-gated channel alpha subunit 10). [provided by Alliance of Genome Resources, Jul 2025]

2 disease mutations (T790A and G1663S) in Nav1.8 that induce nociceptor hyperexcitability increase resurgent currents in DRG neurons which greatly prolong action potential duration and enhance repetitive firing. The transfected G1663S mutation doubled resurgent currents in rat DRGs, and the transfected T790A mutation increased them fourfold. Nav1.8 open-channel block is a major factor in Nav1.8-associated pain mechanisms.

We find that approximately 80% of neurons responsive to cold down to 1 degrees C do not express NaV1.8, and that the genetic deletion of NaV1.8 does not affect the relative number, distribution, or maximal response of cold-sensitive neurons. Furthermore, the deletion of NaV1.8 had no observable effect on transient cold-induced (>/=5 degrees C) behaviors in mice, as measured by the cold-plantar, cold-plate (5 and 10 deg...

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
