Abstract

Objective: The aim of this study was to examine if cholinergic receptor nicotinic beta 3 subunit () was a common genetic basis for both nicotine dependence and schizophrenia.

Methods: Two promoter single nucleotide polymorphisms (SNPs) were genotyped in 773 patients with schizophrenia and 302 healthy volunteers. Associations between smoking, schizophrenia, smoking+schizophrenia and were analyzed. The mRNA expression of in human brains was examined, and the expression correlations between and dopaminergic and GABAergic receptor genes were evaluated.

Results: The association between and smoking was significant in the total sample, less significant in the smoking with schizophrenia, and suggestive in the smoking without schizophrenia. had significant mRNA expression that was correlated with dopaminergic or GABAergic receptor expression in human brains. The two SNPs had significant cis-acting regulatory effects on mRNA expression.

Conclusions: Risk for smoking behavior was associated with . mRNA is abundant in human brain and could play important role in the pathogenesis of smoking behavior.
