Abstract

Purpose

The purpose of this study was to evaluate the association between rs13266634 polymorphism in SLC30A8 gene and type 2 diabetes in Iranian population, and also to provide a way for adjusting the deviation from the Hardy-Weinberg equilibrium.

Methods

This was a case-control study, the patients were selected from the East Azerbaijan province, Iran. In this study, 125 patients with type 2 diabetes (cases) and 125 healthy individuals (controls) were studied. Genotype and allele frequencies were determined in both groups, and the deviations from the Hardy-Weinberg equilibrium were assessed using Bayesian analysis.

Results

A statistically significant association was observed between rs13266634 polymorphism in SLC30A8 gene and type 2 diabetes. In genotype assessing, data analysis showed that, TT genotype play a role in diabetes type 2 risk (P = 0.001). Subjects with TT genotype had a lower risk of diabetes compared to those with CC and CT genotypes. Also, there was no significant relationship between this polymorphism and type 2 diabetes mellitus in the absence of Hardy-Weinberg equilibrium.

Conclusion

Our findings show that, rs13266634 polymorphism was associated with the type 2 diabetes risk in the population of Eastern Azerbaijan province; however, the low number of TT homozygous genotypes affected the precision of the results. Also, the deviation from HWE affected the results. It is recommended to perform further studies to establish Hardy-Weinberg equilibrium. The inconsistency in the results may be due to the ignorance of this equilibrium.
