Entrez Gene Summary for SCN9A Gene

  • 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]

GeneCards Summary for SCN9A Gene

SCN9A (Sodium Channel, Voltage Gated, Type IX Alpha Subunit) is a Protein Coding gene. Diseases associated with SCN9A include neuropathy, hereditary sensory and autonomic, type v and erythermalgia, primary. Among its related pathways are L1CAM interactions and Activation of cAMP-Dependent PKA. GO annotations related to this gene include voltage-gated sodium channel activity and sodium ion binding. An important paralog of this gene is CACNA1D.

UniProtKB/Swiss-Prot for SCN9A Gene

  • Mediates the voltage-dependent sodium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a sodium-selective channel through which Na(+) ions may pass in accordance with their electrochemical gradient. It is a tetrodotoxin-sensitive Na(+) channel isoform. Plays a role in pain mechanisms, especially in the development of inflammatory pain (By similarity).

Tocris Summary for SCN9A Gene

  • Voltage-gated sodium channels (NaV) are responsible for action potential initiation and propagation in excitable cells, including nerve, muscle, and neuroendocrine cell types. They are also expressed at low levels in non-excitable cells, where their physiological role is unclear. Structurally, Nav channels are composed of one pore-forming alpha-subunit, which may be associated with either one or more beta-subunits. alpha-subunits are composed for four homologous domains, each of which contains six transmembrane segments. The fourth transmembrane loop (S4) acts as the voltage sensor and is activated by changes in membrane potential. S4 is also involved in channel gating.

SCN9A_HUMAN
  • Primary erythermalgia (PERYTHM) [MIM:133020]: Autosomal dominant disease characterized by recurrent episodes of severe pain associated with redness and warmth in the feet or hands. {ECO:0000269 PubMed:14985375, ECO:0000269 PubMed:15955112, ECO:0000269 PubMed:15958509, ECO:0000269 PubMed:16216943, ECO:0000269 PubMed:16392115, ECO:0000269 PubMed:18945915, ECO:0000269 PubMed:19369487, ECO:0000269 PubMed:24311784}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Indifference to pain, congenital, autosomal recessive (CIP) [MIM:243000]: A disorder characterized by congenital inability to perceive any form of pain, in any part of the body. All other sensory modalities are preserved and the peripheral and central nervous systems are apparently intact. Patients perceive the sensations of touch, warm and cold temperature, proprioception, tickle and pressure, but not painful stimuli. There is no evidence of a motor or sensory neuropathy, either axonal or demyelinating. {ECO:0000269 PubMed:20635406}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Paroxysmal extreme pain disorder (PEPD) [MIM:167400]: Autosomal dominant paroxysmal disorder of pain and autonomic dysfunction. The distinctive features are paroxysmal episodes of burning pain in the rectal, ocular, and mandibular areas accompanied by autonomic manifestations such as skin flushing. {ECO:0000269 PubMed:17145499, ECO:0000269 PubMed:18945915, ECO:0000269 PubMed:25285947}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Generalized epilepsy with febrile seizures plus 7 (GEFS+7) [MIM:613863]: A rare autosomal dominant, familial condition with incomplete penetrance and large intrafamilial variability. Patients display febrile seizures persisting sometimes beyond the age of 6 years and/or a variety of afebrile seizure types. This disease combines febrile seizures, generalized seizures often precipitated by fever at age 6 years or more, and partial seizures, with a variable degree of severity. {ECO:0000269 PubMed:19763161}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Febrile seizures, familial, 3B (FEB3B) [MIM:613863]: Seizures associated with febrile episodes in childhood without any evidence of intracranial infection or defined pathologic or traumatic cause. It is a common condition, affecting 2-5% of children aged 3 months to 5 years. The majority are simple febrile seizures (generally defined as generalized onset, single seizures with a duration of less than 30 minutes). Complex febrile seizures are characterized by focal onset, duration greater than 30 minutes, and/or more than one seizure in a 24 hour period. The likelihood of developing epilepsy following simple febrile seizures is low. Complex febrile seizures are associated with a moderately increased incidence of epilepsy. {ECO:0000269 PubMed:19763161}. Note=The disease is caused by mutations affecting the gene represented in this entry.
