Sodium channel protein type 4 subunit alpha is a protein that in humans is encoded by the SCN4A gene.^[5]^[6]^[7]^[8]

The Na_v1.4 voltage-gated sodium channel is encoded by the SCN4A gene. Mutations in the gene are associated with hypokalemic periodic paralysis, hyperkalemic periodic paralysis, paramyotonia congenita, and potassium-aggravated myotonia.
