We used urinary biomarkers to test whether two linked lung cancer risk variants in CHRNA3 (rs1051730) and CHRNA5 (rs16969968) are associated with intensity of smoking and exposure to a tobacco-specific carcinogenic nitrosamine per cigarette dose.

We conclude that there are at least two distinct mechanisms conferring risk for nicotine dependence and lung cancer: altered receptor function caused by a D398N amino acid variant in CHRNA5 (rs16969968) and variability in CHRNA5 mRNA expression.

Overall, we did not observe a significant association of each genotype of the two SNPs with risk of gastric cancer (TT/CT vs. CC: adjusted OR = 1.12,95 % CI = 0.86-1.45; p = 0.401 for rs667282 and GG/TG vs. TT: adjusted OR = 1.13,95 % CI = 0.90-1.43; p = 0.300 for rs3743073).The results of our study indicated that these two SNPs at the 15q25 locus did not modify gastric cancer risk and the reported risk SNP at 15q25 may be specific to lung cancer.
