OBJECTIVE: Forty-six nocturnal frontal lobe epilepsy (NFLE) patients (in which the involvement of the CHRNA4 and CHRNB2 genes coding for neuronal nicotinic acetylcholine receptor (nAChRs) subunits associated to the disease were previously excluded) were analyzed for the presence of mutations in the CHRNA2 gene coding for the alpha2 subunit of the same receptor, which has been recently associated with the disease. METHODS: Mutational screening was performed by sequencing two polymerase chain reaction-amplified CHRNA2 DNA fragments, spanning the whole exon 6 and exon 7, respectively, which code for approximately 75% of the mature protein and contain all four transmembrane domains contributing to the ion pore. RESULTS: No mutations were identified in the analyzed region of CHRNA2. CONCLUSIONS: These data demonstrate the rarity of the identified CHRNA2 mutations in NFLE patients, supporting the recently reported hypothesis of a restricted role for this gene in the disease.
