218 aa; Sequence (Fasta) ; (Isoform 2; ) Identical sequences: Pongo abelii: H2NYE4; Pan troglodytes: A5A6L6; A0A663DAR1; K7BT55

Sequence Features

 25D -> N (probable disease-associated variant found in a patient with idiopathic childhood epilepsy; de novo mutation; loss of function in increasing sodium channel activity; dbSNP:rs786205837) VAR_062523 dbSNP
 85R -> H (in ATFB13; the mutant results in highly reduced sodium currents and altered channel gating when coexpressed with SCN5A in a heterologous expression system; dbSNP:rs16969925) VAR_070219 dbSNP
 87E -> Q (probable disease-associated variant found in a patient with non-specific cardiac conduction defects; dbSNP:rs121434627) VAR_062524 dbSNP
 106I -> T (in EIEE52; unknown pathological significance) VAR_078019
 121C -> W (in GEFS+1; can rescue the loss of function and defective trafficking to cell membrane phenotype of the SCN1A variant Thr-1852; dbSNP:rs104894718) VAR_010165 dbSNP
 125R -> C (in EIEE52; severely decreased channel localization at the cell membrane; dbSNP:rs1135401736) VAR_078020 dbSNP
 125R -> L (in GEFS+1; dbSNP:rs759839781) VAR_067341 dbSNP
 138V -> I (in dbSNP:rs72558029) VAR_062525 dbSNP
 153D -> N (in ATFB13; the mutant results in reduced sodium currents when coexpressed with SCN5A in a heterologous expression system; dbSNP:rs72550247) VAR_070220 dbSNP
 208K -> I (in dbSNP:rs780958012) VAR_062526 dbSNP
 211C -> Y (in dbSNP:rs150721582) VAR_062527 dbSNP
