Aim: Some studies showed that tumor necrosis factor gene polymorphism related to the progression of diabetes mellitus. The aim of this study is to explore the correlation between the gene polymorphism of tumor necrosis factor and diabetic retinopathy in clinical cases.
Methods: We took the clinical cases as research subjects. The patients with type I and type II diabetes mellitus who had retinopathy and no retinopathy were 120 cases and 100 cases. At the same time, we analyzed gene polymorphism of tumor necrosis factor for all the patients (rs1800629).
Results: A allelic gene of rs1800629 related to type I diabetes mellitus. We did not find significant correlation between rs1800629 and diabetic retinopathy by adjusting age, gender, duration of diabetes mellitus, HbALc, high blood pressure, kidney disease and other variables.
Conclusion: This study has preliminarily confirmed that functional single nucleotide polymorphism A in promoter region related to type I diabetes mellitus, which had no significant correlation with diabetic retinopathy.
