sodium channel, voltage-gated, type V, alpha (long QT syndrome 3)
Symbol(s):	SCN5A LQT3, CMD1E, Nav1.5
Locus:	3 p21
EC number	[1]
EntrezGene	6331
OMIM	600163
RefSeq	NM_198056
UniProt	Q14524

The Na_v1.5 sodium ion channel protein is encoded by the SCN5A gene. Mutations in the gene are associated with long QT syndrome type 3 (LQT3), Brugada syndrome, and idiopathic ventricular fibrillation.
