Voltage-gated sodium channel, Epilepsy, Dravet syndrome, GEFS , SCN1AAbstract
Voltage-gated ion channels play a pivotal role in cell signaling. They are responsible for generating action potential and repolarization. For this reason, dysfunctions of these channels are more and more often associated with the occurrence of both congenital and acquired neurological diseases, such as epilepsies, migraines, ataxias, or neuromyotonia. Clinical symptoms of neuronal ion channel dysfunction differ significantly, reflecting the role and distribution of a given channel in the central and peripheral nervous systems. This paper re-views voltage-gated sodium channel structure, physiology, mutations, and their role in epilepsy.
