Abstract

We performed genomic mapping of a family with autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) and intellectual and psychiatric problems, identifying a disease-associated region on chromosome 9q34.3. Whole-exome Sequencing identified a mutation in KCNT1, encoding a sodium-gated Potassium Channel subunit. KCNT1 mutations were identified in two additional families and a sporadic case with severe ADNFLE and psychiatric features. These findings implicate the sodium-gated Potassium Channel complex in ADNFLE and, more broadly, in the pathogenesis of focal epilepsies.
