SCN1B (Q07699) variants and mutations

SCN1B (also known as Q07699) is a human protein-coding gene encoding a sodium channel regulatory subunit beta-1 protein. The beta-1 subunit of voltage-gated sodium channels, which regulates channel activity and cell adhesion. Pathogenic variants cause several forms of epilepsy, while associations with cardiac arrhythmias have also been reported. This analysis covers 498 SCN1B variants and mutations. Of these, 91% have computational variant effect predictions. Disease context includes generalized epilepsy with febrile seizures plus, developmental and epileptic encephalopathy, 52, and atrial fibrillation, familial, 13. Example SCN1B variants include M1?, M1I, and M1L.
