== Disease ==
[https://www.uniprot.org/uniprot/SCN2A_HUMAN SCN2A_HUMAN] Defects in SCN2A are the cause of seizures, benign familial infantile type 3 (BFIS3) [MIM:[https://omim.org/entry/607745 607745]. An autosomal dominant disorder in which afebrile seizures occur in clusters during the first year of life, without neurologic sequelae.<ref>PMID:11371648</ref> <ref>PMID:12243921</ref> <ref>PMID:15048894</ref> <ref>PMID:20371507</ref>   Defects in SCN2A are the cause of epileptic encephalopathy early infantile type 11 (EIEE11) [MIM:[https://omim.org/entry/613721 613721]. EIEE11 is an autosomal dominant seizure disorder characterized by infantile onset of refractory seizures with resultant delayed neurologic development and persistent neurologic abnormalities.<ref>PMID:19786696</ref> <ref>PMID:20956790</ref> [https://www.uniprot.org/uniprot/ANK2_HUMAN ANK2_HUMAN] Romano-Ward syndrome. Long QT syndrome 4 (LQT4) [MIM:[https://omim.org/entry/600919 600919]: A heart disorder characterized by a prolonged QT interval on the ECG and polymorphic ventricular arrhythmias. They cause syncope and sudden death in response to exercise or emotional stress, and can present with a sentinel event of sudden cardiac death in infancy. Long QT syndrome type 4 shows many atypical features compared to classical long QT syndromes, including pronounced sinus bradycardia, polyphasic T waves and atrial fibrillation. Cardiac repolarization defects may be not as severe as in classical LQT syndromes and prolonged QT interval on EKG is not a consistent feature. Note=The disease is caused by mutations affecting the gene represented in this entry.<ref>PMID:12571597</ref> <ref>PMID:15178757</ref> 
== Function ==
[https://www.uniprot.org/uniprot/SCN2A_HUMAN SCN2A_HUMAN] 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.[https://www.uniprot.org/uniprot/ANK2_HUMAN ANK2_HUMAN] In skeletal muscle, required for proper localization of DMD and DCTN4 and for the formation and/or stability of a special subset of microtubules associated with costameres and neuromuscular junctions (By similarity). Attaches integral membrane proteins to cytoskeletal elements. Also binds to cytoskeletal proteins. Required for coordinate assembly of Na/Ca exchanger, Na/K ATPase and InsP3 receptor at sarcoplasmic reticulum sites in cardiomyocytes. Required for the coordinated expression of the Na/K ATPase, Na/Ca exchanger and beta-2-spectrin (SPTBN1) in the inner segment of rod photoreceptors. Required for expression and targeting of SPTBN1 in neonatal cardiomyocytes and for the regulation of neonatal cardiomyocyte contraction rate.<ref>PMID:12571597</ref>
