Abstract

Background: The goal of this study is to determine the role of MTHFR (C677T, A1298C) and MGP (G-7A, T-138C) gene variations in DN development.

Methods: There were 61 DN patients and 55 healthy controls in this study. The genotype distributions of these gene variations were determined using PCR and RFLP methods.

Results: According to our study, there was no significant relationship between these gene variations and DN (p > 0.05). The allele frequencies of the MTHFR C677T gene variation in the control group were found significantly different from the Hardy-Weinberg distribution (p < 0.05). According to combined genotype analysis, GA-TT combined genotype of MGP (G-7A/T-138C) gene variations was observed significantly more in the patient group with DN. The GA-TT combined genotype of MGP (G-7A/T-138C) gene variations was differ significantly between these groups (OR: 2.359, %95 CI: 1.094-5.087, p = 0.028).

Conclusion: In our study, although MTHFR and MGP gene variations were not risk factors, the GA-TT combined genotype of the MGP (G-7A/T-138C) gene variation was detected as an important risk factor for DN.
