title: Lack of effect of D2 dopamine receptor TaqI A polymorphism on smoking cessation.
abstract: One previous report (Cinciripini et al., [2004] Nicotine & Tobacco Research, 6, 229-239) found that the D2 dopamine receptor (DRD2) TaqI A polymorphism was associated with smoking cessation: Carriers of the A1 allele were less likely to quit than were those who were not carriers. If confirmed, this finding would allow one to use precessation genotyping to predict the likelihood of successful quitting. The present study reports on results of a similar smoking cessation study and uses the same methods and data analysis in a larger number of smokers. It fails to replicate the effect of DRD2 TaqI A polymorphism on smoking cessation.
