Apolipoprotein E plays an important role in lipid metabolism. We studied the involvement of the APOE gene in the onset of T2DM and its vascular complications. Clinical and biochemical parameters were assessed in each participant. APOE genotypes were identified by PCR-RFLP. Arterial stiffness was studied using a pOpmetre&#174; which evaluates the pulse wave velocity (ft-PWV). Endothelial dysfunction was studied using an EndoPAT2000&#174; which measures endothelium-dependent vasodilation (RHI). In control subjects, the ¦Å3 allele was associated with an increase in fasting blood glucose (r = 2.36, p = 0.018), and a decrease in LDL cholesterol levels (r = &#8722;2.17, p = 0.03), and ¦Å4 was associated with an increase in total cholesterol (r = 2.59, p = 0.01), LDL cholesterol (r = 2.84, p = 0.004), and No-HDL cholesterol (r = 2.74, p = 0.006). In type 2 diabetes subjects, the ¦Å2 was associated with a decrease in diastolic blood pressure (r = &#8722;2.25, p = 0.02). The ¦Å3 was associated with a decrease in ft-PWV (r = &#8722;2.26, p = 0.024) while the ¦Å4 was associated with an increase in ft-PWV (r = 2.52, p = 0.012). Carrying the ¦Å2¦Å3 genotype would have in 99% a limited risk of developing T2DM, and in event of T2DM, only 1 to 2% would have a significant risk of developing atherosclerosis, which would be severe in 17%. Of the ¦Å2¦Å4 genotype, 93% had a limited or even possible risk of developing T2DM, the remaining 7% had a very high risk of developing T2DM. Diabetics carrying ¦Å2¦Å4 had in 7% very high risk of developing atherosclerosis. The latter had a 20% very high risk of being very severe. Subjects carrying the ¦Å3¦Å4 genotype had a 67% possible or even probable risk of developing T2DM and in the event of diabetes, there was in 34% very high risk of developing atherosclerosis which will not have even the time to evolve towards severity. For subjects carrying the ¦Å3¦Å3, the risk of developing T2DM and ath¨¦rosclerosis was higher than that of the ¦Å2¦Å3, and ¦Å2¦Å4 genotypes but lower than that %K < %K i> %K APOE< %K /i> %K Gene %K Polymorphisms %K Type 2 diabetes Mellitus %K Vascular Dysfunctions %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=129410
