We conducted a 1000 Genomes-imputed genome-wide association study (GWAS) meta-analysis for nicotine dependence, defined by the FagerstrΓΆm Test for Nicotine Dependence in 17β074 ever smokers from five European-ancestry samples. We followed up novel variants in 7469 ever smokers from five independent European-ancestry samples. We identified genome-wide significant association in the alpha-4 nicotinic receptor subunit (CHRNA4) gene on chromosome 20q13: lowest P=8.0 Γ 10(-9) across all the samples for rs2273500-C (frequency=0.15; odds ratio=1.12 and 95% confidence interval=1.08-1.17 for severe vs mild dependence). rs2273500-C, a splice site acceptor variant resulting in an alternate CHRNA4 transcript predicted to be targeted for nonsense-mediated decay, was associated with decreased CHRNA4 expression in physiologically normal human brains (lowest P=7.3 Γ 10(-4)). Importantly, rs2273500-C was associated with increased lung cancer risk (N=28β998, odds ratio=1.06 and 95% confidence interval=1.00-1.12), likely through its effect on smoking, as rs2273500-C was no longer associated with lung cancer after adjustment for smoking. Using criteria for smoking behavior that encompass more than the single 'cigarettes per day' item, we identified a common CHRNA4 variant with important regulatory properties that contributes to nicotine dependence and smoking-related consequences.
SNP and indel associations with nicotine dependence from meta-analyses of discovery and independent replication samples, all of European-ancestry. The βlog10 (meta-analysis P) results are plotted by chromosomal position: (a) genome-wide meta-analysis results across the five discovery samples (total N=17 074) for 9.9 million genotyped and imputed SNPs and indels tested for association with nicotine dependence (SNPs shown as circles and indels shown as triangles) with minor allele frequency >0.01 and (b) regional meta-analysis results across all 10 discovery and replication samples (total N=24 543) in the CHRNA4 gene on chromosome 20q13. For the regional plot, the r2 values between the top SNP (rs2273500, shown in purple) and other SNPs in the flanking region were based on the 1000 Genomes European reference panel (denoted EUR); the indels are shown in gray. The solid black lines mark the genome-wide statistical significance threshold (meta-analysis P<5 Γ 10β8). indel, insertion/deletion; SNP, single nucleotide polymorphism.
Association of the rs2273500 minor allele (C) with severe vs mild nicotine dependence across all the samples. rs2273500 had the lowest P-value for its association with nicotine dependence in meta-analysis across all the samples, which are sorted by their size. Black-filled diamonds indicate the discovery samples, and open diamonds indicate the replication samples. The odds ratio (OR) estimates are shown proportional to the sample size.

Associations of the top nicotine dependence-associated SNP rs2273500 with transcript-level and exon-level CHRNA4 mRNA expression in intralobular white matter from 134 European-ancestry participants in the UK Brain Expression Consortium. The probe size (in base pairs) is indicated, and P-values <0.05 are shown in bold. SNP, single nucleotide polymorphism.
