The mean CEA level was significantly higher in hypertensive group (1.63 ng/mL) versus the normotensive group (1.16 ng/mL; p<0.01), in diabetic group (1.87 ng/mL) versus the non-diabetic group (1.18 ng/mL; p<0.01) and in dyslipidemia group (1.58 ng/mL) versus the non-dyslipidemia group (1.19 ng/mL; p = 0.02). The gene discussed is CEACAM5; the disease is metabolic syndrome.
