In the combined analysis, we confirmed two loci to be associated with lung cancer that achieved the threshold of genome-wide significance: 15q25.1 marked by rs2036527 (p=1.3×10(-9); OR=1.32; 95% CI=1.20-1.44) near CHRNA5, and 5p15.33 marked by rs2853677 (p=2.8×10(-9); OR=1.28; 95% CI=1.18-1.39) near TERT.
Associations of SNPs in LOC123688 (rs10519203; odds ratio [OR] = 1.60, 95% confidence interval [CI] = 1.25 to 2.05, P = .00016), CHRNA5 (rs2036527; OR = 1.67, 95% CI = 1.26 to 2.21, P = .00031), and CHRNA3 (rs1051730; OR = 1.81, 95% CI = 1.26 to 2.59, P = .00137) genes with lung cancer risk reached Bonferroni-corrected levels of statistical significance (all statistical tests were two-sided).
