Association between CDKAL1 Gene Polymorphism and Risk of Type 2 Diabetes in Population of Lorestan Province

Diabetes Mellitus is defined as a metabolic disorder characterized by chronic hyperglycemia. The more prevalent form, type 2 diabetes, usually begins as insulin resistance, a disorder in which the cells do not use insulin properly. T2DM is a complex multifactorial disease in which multiple genetic variants interact with environmental factors to trigger the disease. There is sufficient evidence that T2DM has a strong genetic basis. One of the identified candidate genes associated with type 2 diabetes is CDKAL1, reduced expression of CDKAL1 would result in enhanced activity of CDK5 in β cells, which would lead to decreased insulin secretion. In this study, the association of polymorphism rs10946398 of CDKAL1 with type 2 diabetes was evaluated in 200 people by RFLP-PCR method. No significant association was found between the genotypes of polymorphism rs10946398 and type 2 diabetes in the target population. It is suggested that this polymorphism association with type 2 diabetes in larger populations evaluated.
