KCNQ2 is a gene associated with the proper functioning of a potassium channel in the brain. Any changes to the gene are linked with epilepsy.

Seizures related to KCNQ2 can range from mild to severe. In 1998 the condition was associated to a mild illness called “Benign Familial Neonatal Epilepsy” – when a new born baby suffers from seizures, although the attacks stop after a few months.

Over the years further research has revealed KCNQ2 can cover a wide range of epilepsy including KCNQ2 encephalopathy, KCNQ2-related neonatal epileptic encephalopathy, KCNQ2-deficiency syndrome, and KCNQ2-related epilepsy.
