KCNQ3

A gene on chromosome 8q24 that encodes a protein which, with the KCNQ2 protein product, forms the M channel, a slowly activating and deactivating potassium channel central to regulating neuronal excitability.

Molecular pathology
KCNQ2 mutations are associated with benign familial neonatal seizures type 2 (e.g., benign familial neonatal convulsions).
