Presence of C allele showed a positive association with CAD (OR = 2.9; 95% CI [1.65–4.145]; P = .009) and also with dyslipidaemia (OR = 2.95, 95% CI (1.5–4.39); P < .05).Impaired lipid metabolism in carriers of the PPARα Intron 7C allele is possibly responsible for the predilection to CAD. This evidence concerns the gene PPARA and coronary artery disorder.
