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.en10.1007/s40200-022-01061-9info:eu-repo/semantics/openAccessDiabetic NephropathyMTHFR (C677TA1298C) Gene VariationsMGP (G-7AT-138C) Gene VariationsPCRRFLPMatrix Gla ProteinMethylenetetrahydrofolate ReductaseVascular CalcificationPolymorphismsRiskArticle21213171326N/AWOS:0008072981000012-s2.0-8513158121636404848Q2
