Aim: We investigated the effect of PON-1 192 polymorphisms on serum PON1 activity and lipid profiles in 62 non insulin dependent diabetes mellitus (NIDDM) subjects and 69 healthy controls. Patients & Methods: Polymerase chain reaction–based restriction fragment was used to determine PON 192 gene polymorphism. PON activity was measured by spectrophotometric assay. Serum lipid was measured enzymetically. Results: Fasting blood sugar, Total cholesterol, triglycerides, LDL serum level were significantly higher in patient than control. HDL and APOA-1 were low in control than diabetic patients. No significant deference was found in distribution of PON-1 192 polymorphism (QQ, RR and QR) between patients and control subjects. PON-1 192 enzyme activity was significant lower in diabetics than in control subjects. PON-1 192 RR homozygote had significantly low PON-1 192 activity than QQ and QR genotypes among the NIDDM populations (p<0.0001). Conclusion: our results suggest that the paraoxonase activities are affected by PON1 genetic variability in NIDDM patients and controls.
