Key result
Mutations in genes encoding ion channels have been linked to various diseases, including cardiac arrhythmias and epilepsy, providing a basis for understanding pathology and developing therapies.
Understanding channelopathies at the molecular level provides a basis for rational therapeutic approaches.
Does not yet alter arrhythmia or epilepsy management; leaves open mutation-targeted therapy development pending clinical trials.
Diseases as different as cardiac arrhythmias, epilepsy, myotonia, malignant hyperthermia, familial hyperinsulinism, and Bartter syndrome have all been linked to mutations in genes encoding ion channels. This has been made possible by an exciting and fruitful collaboration between clinicians, geneticists, and physiologists. It has led to a more detailed understanding not only of pathology but also of physiology, as the deficiency of a certain gene helps unravel its physiologic role. Some exciting and surprising findings have recently been made in the field of "channelopathies." Understanding these diseases on the molecular level will provide the basis for a rational therapeutic approach to affected patients.

Detlef Böckenhauer (2001) conducted a review in Channelopathies (cardiac arrhythmias, epilepsy, myotonia, malignant hyperthermia, familial hyperinsulinism, Bartter syndrome). Ion channel gene mutations was evaluated. Mutations in genes encoding ion channels have been linked to various diseases, including cardiac arrhythmias and epilepsy, providing a basis for understanding pathology and developing therapies.
