Abstract
Purpose
Diabetic neuropathy (DN) is a serious complication of diabetes that affects peripheral and autonomic nerves, and it has been linked to irregularities in circadian rhythm. Several studies have demonstrated that disruptions in circadian rhythm and changes in expression of rhythm genes may play a role in the development and progression of diabetes, including the development of DN.
Methods
In this study, the association between the VNTR polymorphism of the PER3 gene and diabetic neuropathy was investigated. The study included 84 patients with diabetes, 220 patients with diabetic neuropathy, and 218 healthy individuals as the control group.
Results
Upon analyzing the data from the study, it was found that there was no significant difference in the PER3 VNTR polymorphism between the diabetic neuropathy patients, diabetes and control groups. However, there was a significant difference observed between the control group and the diabetes group, particularly in terms of the 5/5 genotype and 5 alleles. Moreover, a significant difference was observed between the patient group and the control group (p < 0.05).
Conclusions
In conclusion, first in the world, the relationship between PER3 gene VNTR polymorphism and diabetic neuropathy and diabetes, was investigated. Our results showed that PER3 may be associated with diabetes but not with diabetic neuropathy.
