Nocturnal frontal lobe epilepsy (ENFL) is characterized by nocturnal, frequent, brief and stereotypic seizures. Ictal video electroencephalographic (EEG) studies have revealed partial seizures originating from the frontal lobe but also in parts of the insula, suggesting a defect of a broader network. Mutations in CHRNA4, CHRNB2, and CHRNA2, which encodes the alpha4-, beta2-, and alpha2-subunit of neuronal nicotinic acetylcholine receptor, have been reported. These mutations are concentrated in the pore-forming M2 transmembrane segments.
