This study includes a Spanish population (n=417) of three groups based on their alcohol consumption; abstainers (n=142), moderate (<280 g/week, n=111) and heavy drinkers (> 280 g/week, n=164). 20 tag SNPs in five nicotine receptor subunit genes (CHRNA3, 4, and 6; CHRNB2 and 3) were genotyped and analysed for single marker and haplotype associations.

We demonstrate here that alpha2-I279N can be co-expressed with the major structural subunit CHRNB2. alpha2-I279N causes a marked gain-of-function effect and displays a distinct biopharmacological profile, including markedly reduced inhibition by carbamazepine and increased nicotine sensitivity.

J Neurosci. 2008 Nov 19;28(47):12465-76.


Mutations of genes encoding alpha4, beta2, or alpha2 subunits (CHRNA4, CHRNB2, or CHRNA2, respectively) of nAChR [neuronal nicotinic ACh (acetylcholine) receptor] cause nocturnal frontal lobe epilepsy (NFLE) in human.
