No genome-wide significant association of AhR/Wnt-genes with overall lung cancer was observed, but within the subgroups of ever smokers (e.g., maker rs2722278 SFRP4; OR  = 1.20; 95% CI 1.13–1.27; p  = 5.6 × 10–10) and never smokers (e.g., maker rs1133683 Axin2; OR  = 1.27; 95% CI 1.19–1.35; p  = 1.0 × 10–12). The gene discussed is AHR; the disease is lung carcinoma.
