Mutations in nAChRs are found in a rare form of nocturnal frontal lobe epilepsy. Previously, some nAChR mutations have been described that are associated with additional neurological features such as psychiatric disorders or cognitive defects. A new CHRNB2 mutation located in transmembrane region 3 (M3), outside the known ADNFLE mutation cluster. The CHRNB2 mutation I312M, which occurred de novo in twins, markedly increases the receptor's sensitivity to acetylcholine. Phenotypically, the mutation is associated not only with typical ADNFLE, but also with distinct deficits in memory. The cognitive problems are most obvious in tasks requiring the organization and storage of verbal information.

For background information on the acetylcholine receptor (AChR), see CHRNA1. Two forms of AChR are found in mammalian skeletal muscle cells. The mature form is predominant in innervated adult muscle and the embryonic form is present in fetal and denervated muscle. Embryonic and mature AChR differ by the replacement of the gamma subunit in the pentameric glycoprotein complex by its isoform, the epsilon subunit, which is specific to the mature AChR subtype. This switch is mediated by ARIA (acetylcholine receptor-inducing activity.For background information on the acetylcholine receptor (AChR), see CHRNA1 (MIM 100690).
