Entrez Gene summary for SCN1A:
The vertebrate sodium channel is a voltage-gated ion channel essential for the generation and propagation of action
potentials, mainly in nerve and muscle. Voltage-sensitive sodium channels are heteromeric complexes consisting of a
large central pore-forming glycosylated alpha subunit, and two smaller auxiliary beta subunits. This gene encodes the
large alpha subunit, and mutations in this gene have been associated with several epilepsy, convulsion and migraine
disorders. Alternative splicing results in multiple transcript variants. The RefSeq Project has decided to create four
representative RefSeq records. Three of the transcript variants are supported by experimental evidence and the fourth
contains alternate 5' untranslated exons, the exact combination of which have not been experimentally confirmed for
the full-length transcript.(provided by RefSeq, Jan 2011)

UniProtKB/Swiss-Prot: SCN1A_HUMAN, P35498
Function: 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

summary for SCN1A:
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.

  • Defects in SCN1A are the cause of generalized epilepsy with febrile seizures plus type 2 (GEFS+2)
  • [MIM:604403]. Generalized epilepsy with febrile seizures-plus refers to 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. GEFS+ is a disease combining febrile seizures,
    generalized seizures often precipitated by fever at age 6 years or more, and partial seizures, with a variable degree
    of severity
  • Defects in SCN1A are a cause of severe myoclonic epilepsy in infancy (SMEI) [MIM:607208]; also called Dravet
  • syndrome. SMEI is a rare disorder characterized by generalized tonic, clonic, and tonic-clonic seizures that are
    initially induced by fever and begin during the first year of life. Later, patients also manifest other seizure types,
    including absence, myoclonic, and simple and complex partial seizures. Psychomotor development delay is observed
    around the second year of life. SMEI is considered to be the most severe phenotype within the spectrum of generalized
    epilepsies with febrile seizures-plus
  • Defects in SCN1A are a cause of intractable childhood epilepsy with generalized tonic-clonic seizures (ICEGTC)
  • [MIM:607208]. ICEGTC is a disorder characterized by generalized tonic-clonic seizures beginning usually in infancy and
    induced by fever. Seizures are associated with subsequent mental decline, as well as ataxia or hypotonia. ICEGTC is
    similar to SMEI, except for the absence of myoclonic seizures
  • Defects in SCN1A are the cause of familial hemiplegic migraine type 3 (FHM3) [MIM:609634]. FHM3 is an
  • autosomal dominant severe subtype of migraine with aura characterized by some degree of hemiparesis during the
    attacks. The episodes are associated with variable features of nausea, vomiting, photophobia, and phonophobia. Age at
    onset ranges from 6 to 15 years. FHM is occasionally associated with other neurologic symptoms such as cerebellar
    ataxia or epileptic seizures. A unique eye phenotype of elicited repetitive daily blindness has also been reported to
    be cosegregating with FHM in a single Swiss family
  • Defects in SCN1A are the cause of familial febrile convulsions type 3A (FEB3A) [MIM:604403]; also known as
  • familial febrile seizures 3. Febrile convulsions are 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
