iMedPub Journals Abstract BACKGROUND Endothelial nitric oxide synthase eNOS plays a major role in the response of anti-hypercholesterol statin drugs Genetic polymorphisms in eNOS gene affect eNOS s activity and hence modulate statins response OBJECTIVES This study investigated the influence of major functional eNOS gene polymorphisms rs2070744 rs1799983 and rs61722009 on the lipid profile of diabetes mellitus type 2 T2DM Jordanian patients on atorvastatin treatment METHOD One hundreds and three T2DM patients attending the diabetic clinic of Jordan University Hospital were enrolled in this study The T2DM patients were on 20 mg atorvastatin The atorvastatin response was calculated through measuring the lipid profile before and after 3 months of atorvastatin treatment The eNOS genotypes of the patients were analyzed using polymerase chain reaction followed by restriction fragment length polymorphism assay method RESULTS There was no significant association between eNOS genetic polymorphisms and the response to atorvastatin ANOVA p value 0 05 However patients with eNOS rs1799983 4a 4a and rs61722009 G G genotypes have a significant p value 0 05 lower total cholesterol TC and low density lipoprotein LDL baseline than patients carrying rs1799983 4b 4b and rs61722009 T T genotypes The eNOS rs1799983 and rs61722009 polymorphisms were in complete D 1 linkage disequilibrium CONCLUTION Although we did not find an association between eNOS genetic polymorphisms and atorvastatin response there was a significant association between rs1799983 and rs61722009 genotypes and TC and LDL baseline levels in Jordanian T2DM These genetic variants affect the cholesterol level and may play a role in the susceptibility to cardiovascular diseases among T2DM in Jordan Further intensive studies are needed to validate these findings
