Polymorphism rs564398 of the ANRIL Gene as a Coronary-Artery-Disease-Associated SNP in Diabetic Patients of the Kazakh Population.

Background/objectives: A cardiovascular complication of type 2 diabetes mellitus like coronary artery disease is influenced by a complex interplay between environmental, phenotypic, and genetic factors. The genetic mechanisms in the development of this pathology are not established. This study aims to evaluate the association of polymorphisms rs1011970, rs62560775, and rs564398 from the 9p21.3 locus with coronary artery disease in diabetic patients of the Kazakh population.

Methods: A total of 343 people participated in the case-control study: the control group consisted of 109 people with type 2 diabetes and coronary artery disease, while the control group included 234 people. Genotyping was performed using real-time PCR. Statistical analysis was carried out using Chi-square methods and calculating odds ratios (OR) with 95% confidence intervals (CI).

Results: According to the results, only the rs564398 polymorphism of the ANRIL gene was associated with coronary artery disease ( = 0.04). The CC genotype increased the risk of developing coronary artery disease by more than 1.5 times (1.62 (1.02-2.56)), whereas the TT genotype reduced the risk of coronary artery disease (0.39 (0.17-0.91)). The remaining polymorphisms, rs1011970 and rs62560775, were not associated with coronary artery disease.

Conclusions: Thus, this research further elicits the association of the ANRIL gene with cardiometabolic disease.
