Previously, preliminary results indicated that there was an association between IKZF2 rs12619285 and CHD in the Chinese Han population [G allele frequency, 62.8%; P=0.07; odds ratio (OR), 1.38, 95% confidence interval (CI), 0.97–1.98], with no departure from the Hardy-Weinberg equilibrium (HWE) in the controls (22). The gene discussed is IKZF2; the disease is coronary artery disorder.
