In the Caucasian subgroup, no significant association was detected between CDKN2B‐AS1 gene rs4977574 A/G polymorphism and CHD under allelic (OR: 1.18, 95% CI: 0.96–1.46, p = 0.12), recessive (OR: 1.40, 95% CI: 0.93–2.11, p = 0.11), dominant (OR: 0.70, 95% CI: 0.45–1.11, p = 0.13), heterozygous (OR: 1.175, 95% CI: 0.928–1.489, p = 0.181), homozygous (OR: 1.393, 95% CI: 0.913–2.124, p = 0.124) and additive (OR: 1.182, 95% CI: 0.956–1.461, p = 0.122) genetic models. The gene discussed is CDKN2B; the disease is coronary artery disorder.
