CYP24A1 and coronary artery disorder: CYP24A1 rs6068816 was also linked with higher susceptibility to CHD in the subgroup of men (homozygote: OR = 2.03, 95% CI = 1.21–3.40, P = 0.007; dominant: OR = 1.42, 95% CI = 1.04–1.93, P = 0.028; recessive: OR = 1.77, 95% CI = 1.09–2.88, P = 0.022; additive: OR = 1.38, 95% CI = 1.10–1.74, P = 0.006; allele: OR = 1.37, 95% CI = 1.09–1.72, P = 0.007) and smokers (homozygote: OR = 3.02, 95% CI = 1.31–6.99, P = 0.010; recessive: OR = 2.60, 95% CI = 1.17–5.78, P = 0.019; additive: OR = 1.57, 95% CI = 1.11–2.23, P = 0.011; allele: OR = 1.61, 95% CI = 1.15–2.27, P = 0.006).
