Markers in the 15q24 nicotinic receptor subunit gene cluster (CHRNA5‐A3‐B4) predict severity of nicotine addiction and response to smoking cessation therapy
Meta-analysisN=19,747Jane E. Sarginson et al.(2011)· American Journal of Medical Genetics Part B: Neuropsychiatric Genetics

This PhD thesis comprehensively explores associations between the CHRNA5-A3-B4 nicotinic acetylcholine receptor gene cluster and smoking-related behaviors. Using systematic review/meta-analysis, genetic epidemiology, laboratory-based techniques, and genome-wide meta-analysis, the study found compelling evidence for a small, robust association between rs16969968/rs1051730 and daily cigarette consumption with a per-allele effect of approximately one cigarette per day (beta≈1.0). A genome-wide meta-analysis of cotinine levels in 2,139 current smokers identified multiple variants in the CHRNA5 region strongly associated with tobacco exposure. However, no association was observed with smoking initiation in a prospectively-assessed cohort.
