N2 - A common variant on chromosomal region 15q24-25.1, marked by rs1051730, was found to be associated with lung cancer risk. Here, we attempted to confirm the second variant on 15q24-25.1 in several large sporadic lung cancer populations and determined what percentage of additional risk for lung cancer is due to the genetic effect of the second variant. SNPs rs1051730 and rs481134 were genotyped in 2,818 lung cancer cases and 2,766 controls from four populations. Joint analysis of these two variants (rs1051730 and rs481134) on 15q24-25.1 identified three major haplotypes (G-T, A-C, and G-C) and provided stronger evidence for association of 15q24-25.1 with lung cancer (P = 9.72 x 10-9). These two variants represent three levels of risk associated with lung cancer. The most common haplotype G-T is neutral; the haplotype A-C is associated with increased risk for lung cancer with 5.0% higher frequency in cases than in controls [P = 1.68 x 10-7; odds ratio (OR), 1.24; 95% confidence interval (95% CI), 1.14-1.35]; whereas the haplotype G-C is associated with reduced risk for lung cancer with 4.4% lower frequency in cases than in controls (P = 7.39 x 10-7; OR, 0.80; 95% CI, 0.73-0.87). We further showed that these two genetic variants on 15q24-25.1 independently influence lung cancer risk (rs1051730: P = 4.42 x 10-11; OR, 1.60; 95% CI, 1.46-1.74; rs481134: P = 7.01 x 10-4; OR, 0.81; 95% CI, 0.72-0.92). The second variant on 15q24-25.1, marked by rs481134, explains an additional 13.2% of population attributable risk for lung cancer.
