However, smokers with mutated homozygous rs6068816 in CYP24A1 had significantly decreased NSCLC risk (OR = 0.43, 95% CI 0.27–1.02; p = 0.006); and smokers and non-smokers with mutated homozygous rs1544410 in VDR had significantly decreased NSCLC risk (OR = 0.51, 95% CI 0.34–1.17; p = 0.002; OR = 0.26, 95% CI 0.20–0.69; p = 0.001, respectively). The gene discussed is VDR; the disease is non-small cell lung carcinoma.
