Association of Genetically Predicted Activity of AMP Deaminase 1 with Clinical and Biochemical Parameters in Diabetic Individuals with Coronary Artery Disease.

Some reports indicated the association of rs17602729 and rs34526199 functional polymorphisms of the gene encoding adenosine monophosphate deaminase 1 (AMPD1) with the risk of coronary artery disease (CAD) and/or its intermediate phenotype. Therefore, the aim of our study was to analyze the association of both polymorphisms with the predisposition to disease and both clinical and biochemical phenotypes but solely in diabetic individuals with CAD. The study group consisted of 196 adult diabetic individuals with CAD, and the control group comprised 200 healthy newborns. Both polymorphisms were identified by a SNaPshot minisequencing reaction. Clinical and laboratory data were taken from patients' records. There were no significant differences between both groups in the frequency distributions of :rs17602729 and rs34526199 alleles or genotypes. BMI and the frequency of obesity in TT rs17602729 homozygotes (no AMPD1 activity) were significantly lower and the serum concentration of HDL cholesterol was significantly higher compared to other patients. The concentrations of total cholesterol and LDL cholesterol in homozygotes for wild-type :rs17602729 (c.34C) and rs34526199 (c.860A) alleles (full AMPD1 activity) were significantly lower compared to its values in other patients. Our results suggest that genetically predicted activity of AMPD1 is associated with variation in body mass and lipid metabolism in diabetic Polish people with CAD.
