As far as we know, the result of a previous meta-analysis showed that there was no significant association between CYP2J2 G-50T polymorphism and CAD risk in dominant model comparisons (OR = 1.12, 95% CI = 0.95–1.31) and additive model comparisons (OR = 1.15, 95% CI = 0.97–1.36) [13]. Here, CYP2J2 is linked to coronary artery disorder.
