KCNQ4, a novel potassium channel expressed in sensory outer hair cells, is mutated in dominant deafness.

Potassium channels regulate electrical signaling and the ionic composition of biological fluids. Mutations in the three known genes of the KCNQ branch of the K+ channel gene family underlie inherited cardiac arrhythmias (in some cases associated with deafness) and neonatal epilepsy. We have now clon... View More
