Abstract

Background: Type 2 diabetes is a common multifactorial disease that has been studied by researchers in this century. These studies show the importance and position of genetics in relation to diabetes. The purpose of this study is to investigate the prevalence of rs5219 and rs5215 polymorphisms in the familial type 2 diabetic population of Yazd province. Methods: This study is a case-control study that was conducted on 200 people (100 type 2 diabetes patients with a positive family history of type 2 diabetes and 100 healthy people without a family history of diabetes). In this study, using the ARMS-PCR technique, the genotype of the patient group and the control group were examined, and dispersion indices and parametric statistical tests such as P-value and Chi-square were used to determine the significant relationship between diabetes and genetics. Results: Statistical analysis showed that there is a significant difference between the allelic and genotypic frequencies in both patient and control groups in rs5215 polymorphism with P=0.0015 and in rs5219 polymorphism with P=0.0342. Conclusion: The present study showed that rs5215 and rs5219 polymorphism of KCNJ11 gene can be related to type 2 diabetes in the population of Yazd province, although extensive studies are needed to confirm these results. © 2024 Iranian Journal of Diabetes and Metabolism and Tehran University of Medical Sciences.
