GENE - TERM ANNOTATION REPORT

RGD ID: 69368
Species: Rattus norvegicus
RGD Object: Gene
Symbol: Scn9a
Name: sodium voltage-gated channel alpha subunit 9
Acc ID: DOID:9002272
Term: Small Fiber Neuropathy
Definition: Disorder of the peripheral nerves that primarily impair small nerve fibers. The affected small nerve fibers include myelinated A-delta fibers (see A FIBERS) and unmyelinated C FIBERS. Because these small fibers innervate skin and help control autonomic function, their neuropathy presents with neuropathic pain, reduced thermal and pain sensitivity, and autonomic dysfunction (e.g. abnormal sweating or facial flushing). Small fiber neuropathy can be idiopathic or associated with underlying diseases (e.g., AMYLOIDOSIS; DIABETES MELLITUS; SARCOIDOSIS; or VASCULITIS).
Definition Source(s): MESH:D000071075
Note: Use of the qualifier "multiple interactions" designates that the annotated interaction is comprised of a complex set of reactions and/or regulatory events, possibly involving additional chemicals and/or gene products.
