Summaries for SCN5A Gene

Entrez Gene Summary for SCN5A Gene

  • The protein encoded by this gene is an integral membrane protein and tetrodotoxin-resistant voltage-gated sodium channel subunit. This protein is found primarily in cardiac muscle and is responsible for the initial upstroke of the action potential in an electrocardiogram. Defects in this gene are a cause of long QT syndrome type 3 (LQT3), an autosomal dominant cardiac disease. Alternative splicing results in several transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

GeneCards Summary for SCN5A Gene

SCN5A (Sodium Voltage-Gated Channel Alpha Subunit 5) is a Protein Coding gene. Diseases associated with SCN5A include Long Qt Syndrome 3 and Brugada Syndrome 1. Among its related pathways are Cardiac conduction and L1CAM interactions. Gene Ontology (GO) annotations related to this gene include protein kinase binding and ubiquitin protein ligase binding. An important paralog of this gene is SCN2A.

UniProtKB/Swiss-Prot for SCN5A Gene

  • This protein 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-resistant Na(+) channel isoform. This channel is responsible for the initial upstroke of the action potential. Channel inactivation is regulated by intracellular calcium levels.

Tocris Summary for SCN5A 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.

  • Atrial fibrillation, familial, 10 (ATFB10) [MIM:614022]: A familial form of atrial fibrillation, a common sustained cardiac rhythm disturbance. Atrial fibrillation is characterized by disorganized atrial electrical activity and ineffective atrial contraction promoting blood stasis in the atria and reduces ventricular filling. It can result in palpitations, syncope, thromboembolic stroke, and congestive heart failure. {ECO:0000269 PubMed:18088563, ECO:0000269 PubMed:18378609}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Atrial standstill 1 (ATRST1) [MIM:108770]: A rare arrhythmia characterized by the absence of electrical and mechanical activity in the atria. Electrocardiographically, it is characterized by bradycardia, the absence of P waves, and a junctional narrow complex escape rhythm. {ECO:0000269 PubMed:12522116}. Note=The disease may be caused by mutations affecting distinct genetic loci, including the gene represented in this entry. A mutation in SCN5A has been detected in combination with a rare GJA5 genotype in a large family with atrial standstill.
  • Brugada syndrome 1 (BRGDA1) [MIM:601144]: A tachyarrhythmia characterized by right bundle branch block and ST segment elevation on an electrocardiogram (ECG). It can cause the ventricles to beat so fast that the blood is prevented from circulating efficiently in the body. When this situation occurs, the individual will faint and may die in a few minutes if the heart is not reset. {ECO:0000269 PubMed:10532948, ECO:0000269 PubMed:10618304, ECO:0000269 PubMed:10690282, ECO:0000269 PubMed:11410597, ECO:0000269 PubMed:11748104, ECO:0000269 PubMed:11823453, ECO:0000269 PubMed:11901046, ECO:0000269 PubMed:12051963, ECO:0000269 PubMed:12106943, ECO:0000269 PubMed:15023552, ECO:0000269 PubMed:15338453, ECO:0000269 PubMed:15579534, ECO:0000269 PubMed:15851320, ECO:0000269 PubMed:16266370, ECO:0000269 PubMed:16325048, ECO:0000269 PubMed:16616735, ECO:0000269 PubMed:17075016, ECO:0000269 PubMed:17081365, ECO:0000269 PubMed:17198989, ECO:0000269 PubMed:18252757, ECO:0000269 PubMed:18341814, ECO:0000269 PubMed:18451998, ECO:0000269 PubMed:18456723, ECO:0000269 PubMed:18616619, ECO:0000269 PubMed:19251209, ECO:0000269 PubMed:19272188, ECO:0000269 PubMed:20129283, ECO:0000269 PubMed:23085483, ECO:0000269 PubMed:24167619, ECO:0000269 PubMed:26279430, ECO:0000269 PubMed:26776555, ECO:0000269 PubMed:9521325}.

  • Cardiomyopathy, dilated 1E (CMD1E) [MIM:601154]: A disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death. {ECO:0000269 PubMed:15466643}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Familial paroxysmal ventricular fibrillation 1 (VF1) [MIM:603829]: A cardiac arrhythmia marked by fibrillary contractions of the ventricular muscle due to rapid repetitive excitation of myocardial fibers without coordinated contraction of the ventricle and by absence of atrial activity. {ECO:0000269 PubMed:10940383}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Long QT syndrome 3 (LQT3) [MIM:603830]: 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. {ECO:0000269 PubMed:10377081, ECO:0000269 PubMed:10508990, ECO:0000269 PubMed:10590249, ECO:0000269 PubMed:10627139, ECO:0000269 PubMed:10911008, ECO:0000269 PubMed:10973849, ECO:0000269 PubMed:11304498, ECO:0000269 PubMed:11410597, ECO:0000269 PubMed:11710892, ECO:0000269 PubMed:11889015, ECO:0000269 PubMed:11997281, ECO:0000269 PubMed:12209021, ECO:0000269 PubMed:12454206, ECO:0000269 PubMed:12673799, ECO:0000269 PubMed:15840476, ECO:0000269 PubMed:16414944, ECO:0000269 PubMed:16922724, ECO:0000269 PubMed:18060054, ECO:0000269 PubMed:18451998, ECO:0000269 PubMed:18708744, ECO:0000269 PubMed:18848812, ECO:0000269 PubMed:18929331, ECO:0000269 PubMed:19716085, ECO:0000269 PubMed:26392562, ECO:0000269 PubMed:7651517, ECO:0000269 PubMed:7889574, ECO:0000269 PubMed:8541846, ECO:0000269 PubMed:9506831, ECO:0000269 PubMed:9686753, ECO:0000269 Ref.32}.

  • Progressive familial heart block 1A (PFHB1A) [MIM:113900]: A cardiac bundle branch disorder characterized by progressive alteration of cardiac conduction through the His-Purkinje system, with a pattern of a right bundle-branch block and/or left anterior hemiblock occurring individually or together. It leads to complete atrio-ventricular block causing syncope and sudden death. {ECO:0000269 PubMed:11234013, ECO:0000269 PubMed:11804990, ECO:0000269 PubMed:12569159, ECO:0000269 PubMed:12574143, ECO:0000269 PubMed:19251209}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Sick sinus syndrome 1 (SSS1) [MIM:608567]: The term sick sinus syndrome encompasses a variety of conditions caused by sinus node dysfunction. The most common clinical manifestations are syncope, presyncope, dizziness, and fatigue. Electrocardiogram typically shows sinus bradycardia, sinus arrest, and/or sinoatrial block. Episodes of atrial tachycardias coexisting with sinus bradycardia (tachycardia-bradycardia syndrome) are also common in this disorder. SSS occurs most often in the elderly associated with underlying heart disease or previous cardiac surgery, but can also occur in the fetus, infant, or child without heart disease or other contributing factors. SSS1 onset is in utero, infancy, or early childhood. {ECO:0000269 PubMed:11748104, ECO:0000269 PubMed:14523039, ECO:0000269 PubMed:22795782}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Sudden infant death syndrome (SIDS) [MIM:272120]: SIDS is the sudden death of an infant younger than 1 year that remains unexplained after a thorough case investigation, including performance of a complete autopsy, examination of the death scene, and review of clinical history. Pathophysiologic mechanisms for SIDS may include respiratory dysfunction, cardiac dysrhythmias, cardiorespiratory instability, and inborn errors of metabolism, but definitive pathogenic mechanisms precipitating an infant sudden death remain elusive. {ECO:0000269 PubMed:18596570, ECO:0000269 PubMed:19302788}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
