Target Background

Regulatory subunit of multiple voltage-gated sodium channel complexes that play important roles in excitable membranes in brain, heart and skeletal muscle. Enhances the presence of the pore-forming alpha subunit at the cell surface and modulates channel gating characteristics and the rate of channel inactivation. Modulates the activity of multiple pore-forming alpha subunits, such as SCN1A, SCN2A, SCN3A, SCN4A, SCN5A and SCN10A.; Cell adhesion molecule that plays a critical role in neuronal migration and pathfinding during brain development. Stimulates neurite outgrowth. Has no regulatory function on the SCN2A sodium channel complex.

  1. we confirm the recessive inheritance of 2 novel SCN1B mutations in 5 children from 3 families with developmental epileptic encephalopathy. The recessive inheritance and early death in these patients is consistent with the Dravet-like phenotype observed in Scn1b(-/-) mice. PMID: 28218389
  2. This report provides the first genetic evidence of SCN1B mutation causing the Benign Familial Infantile Epilepsy (BFIE) phenotype. PMID: 28566192
  3. Contribution of Cardiac Sodium Channel beta-Subunit Variants to Brugada Syndrome. PMID: 26179811
  4. SCN1B gene mutations that reduce sodium channel current may provide a mechanistic link between Atrioventricular nodal reentrant tachycardia and Brugada syndrome and predispose to expression of both phenotypes. PMID: 25998140
  5. In a nonreferred nationwide Danish cohort of SIDS cases, up to 5/66 (7.5%) of SIDS cases can be explained by genetic variants in the sodium channel complex genes. PMID: 25757662

  9. High SCN1B expression is associated with increased tumour growth and metastasis in breast cancer. PMID: 24729314
  10. Hippocampal networks of a NaV beta1 transgenic mouse model of genetic epilepsy show enhanced excitability. PMID: 24605816
  11. experimental data indicate that sodium channel voltage-gated type I beta subunit (Navbeta1b)/H162P results in reduced sodium channel activity functionally affecting the ventricular action potential. PMID: 24561865
  12. SCN1B mutation is not a common cause of Dravet syndrome. PMID: 23182416
  13. results suggest that R214Q variation in SCN1Bb is a functional polymorphism that may serve as a modifier of the substrate responsible for Brugada syndrome or SIDS phenotypes PMID: 22155597
  14. Our study supports the association of SCN1Bb with BrS. PMID: 22284586
  15. A novel seizure-causing mechanism is suggested for NaV1.2beta1 in patients harboring mutant C121W subunit: increased channel excitability at elevated temperature. PMID: 22292491
  16. SCN1B is the gene responsible in one out of six Tunisian families with febrile seizures (FS) that may contribute susceptibility for the five others. PMID: 21040232
  17. This study demonstrated that SCN1B may not be related to the occurrence of benign partial epilepsy in infancy or convulsions with gastroenteritis. PMID: 21882141
  18. The results suggested that beta1B p.G257R may contribute to epilepsy through a mechanism that includes intracellular retention resulting in aberrant neuronal pathfinding. PMID: 21994374
  19. Enhanced tubulin polymerization reduces sarcolemmal Na(v)1.5 expression and I(Na) amplitude in a beta1-subunit-independent fashion and causes I(Na) fast and slow inactivation impairment in a beta1-subunit-dependent way PMID: 19861310
  20. The IVS3+ 2996(TTA)8 allele in SCN1B commonly seen in Japanese would not be pathogenic itself but may render male, middle-aged Japanese more susceptible to Brugada syndrome PMID: 20137763
  21. Mutation of the sodium channel subunit SCN1B linked again to generalized epilepsy with febrile seizures PMID: 12011299
  22. Functional and biochemical analysis of a sodium channel beta1 subunit mutation responsible for generalized epilepsy with febrile seizures plus type 1. PMID: 12486163
  23. the expression of NaCh beta1 subunit protein in astrocytes is plastic, and indicate a novel mechanism for modulation of glial function in gliosis-associated pathologies. PMID: 12677453
  24. The IVS2-2A>C transition deletes AA 70-74 in the central hydrophobic core of the extracellular Ig domain, disrupting the hydrophobic interaction in the Ig-like fold & proper [beta]1 folding & causing a persistent inward Na+ current & hyperexcitability. PMID: 14504340
  25. identification and characterization of a novel splicing variant; functional studies in oocytes demonstrate that the beta1B subunit increases the ionic current when coexpressed with the tetrodotoxin sensitive channel, NaV1.2 PMID: 14622265
  26. Although data suggest that SCN1B activity does not directly influence membrane potential, intracellular Ca(2+) release, or proliferation in normal human pulmonary artery smooth muscle cells, its physiological functions remain unresolved. PMID: 16052353
  27. Use of these Na+ channel models in simple neuron models revealed that both mutations(R85C, R85H) cause an increase in excitability but the R85H mutation was more excitable. PMID: 17604911
  28. In summary, the mutant beta1 subunits essentially fail to modulate alpha subunits which could increase neuronal excitability and underlie GEFS+ pathogenesis. PMID: 17629415
  29. This suggests that mutations in the SCN1B gene is not a prevalent cause of familial cases of FS and epilepsy or GEFS+ in Scandinavia. PMID: 17927801
  30. SCN1B mutations were not found to directly cause long QT syndrome. PMID: 18052691
