Logistic regression was used to observe association of SNP within PPARG and CYP1A1 with CAD risk and GMDR model was used to screen the best interaction combinations.
Moreover, it also shows the effect of smoking-gene interaction on CAD risk, where the CYP1A1 MspI polymorphism revealed a decreased risk in current smokers.
1.The CYP1A1T6235C polymorphism (rs4646903) gene polymorphism has been linked to the development of coronary heart disease and cigarette smoking-related lung cancer.
Compared to the A/A genotype, the multivariate logistic regression analysis showed that carrying the CYP1A1 2C G/G genotype was associated with a significantly decreased risk for CAD (OR=0.32, 95% CI=0.15-0.70).
