WebChannelopathies Definition Channelopathies are inherited diseases caused by defects in cell proteins called ion channels. Channelopathies include a wide range of neurologic … WebIon channelopathies are a group of rare genetic conditions. This is caused by a genetic alteration (variant), which affects ion channels in the heart. These channels are on each individual cell wall within the heart muscle. They provide a route into and out of cells, via the cell wall, of chemical substances (ions).
