In this study, we compared genetic variants influencing the effect of smoking on COPD, that is, the effect of the well-known splicing defect polymorphism, CYP3A5*3 (rs776746), identified before genome-wide association studies, with the genome-wide association studies identified CHRNA3 (rs1051730) polymorphism on the risk of decreased lung function and COPD.MATERIALS AND METHODS: In all, 10 605 participants from the general population were genotyped. Information on spirometry, hospital admissions and smoking behaviour was recorded. Endpoints were lung function and COPD.RESULTS: For CHRNA3, the percentage of forced expiratory volume in 1 s (FEV1{\%}) predicted was 89.3, 90.6 and 92.4{\%} in homozygous, heterozygous and noncarrier ever-smokers (P-trend<0.001). The corresponding values for forced vital capacity percentage (FVC{\%}) predicted were 94.5, 95.2 and 96.7{\%} (P-trend<0.001), and for FEV1/FVC ratio, the values were 0.753, 0.760 and 0.764 (P-trend=0.008). The odds ratio for COPD in homozygous versus noncarrier ever-smokers was 1.5 [95{\%} confidence interval (CI) 1.3-1.9] for COPD hospitalization, 1.3 (95{\%} CI 1.1-1.6) for COPD defined as FEV1/FVC less than lower limit of normal, 1.3 (95{\%} CI 1.0-1.5) for the Global Initiative for Chronic Obstructive Lung Disease category 1-4 (GOLD 1-4), 1.2 (95{\%} CI 1.0-1.5) for GOLD 2-4 and 1.5 (95{\%} CI 1.1-2.2) for GOLD 3-4.
