Six SNPs, PPP1R13L rs1970764 [OR, Odd Ratio (95% CI,) = 1.58 (1.09-2.29), P = 0.014] in the recessive model and PPP1R13L rs1005165 [OR (95% CI) = 1.25 (1.01-1.54), P = 0.036], CD3EAP rs967591 [OR (95% CI) = <1.40 (1.13-1.75), P = 0.0023], rs735482 [OR (95% CI) = 1.29 (1.03-1.61), P = 0.026], rs1007616 [OR (95% CI) = 0.78 (0.61-1.00), P = 0.046], and rs62109563 [OR (95% CI) = 1.28 (1.03-1.59), P = 0.024] in the log-additive model, were associated with increased lung cancer risk. This evidence concerns the gene POLR1G and lung carcinoma.
