Sodium - Sophion

Sodium channels

Sodium channels are highly selective for the transport of sodium ions across cell membranes.

Sodium channels are associated with a large range of channelopathies among others epilepsy, Dravet syndrome, West syndrome, Irritable bowel syndrome, long QT syndrome, neuropsychiatric disorders, pain and insensitivity to pain.
