Abstract

Diabetic foot syndrome (DFS) represents a complex and severe complication of diabetes mellitus, involving peripheral neuropathy, micro- and macrovascular dysfunction, and infection. Endothelial dysfunction plays a central role in its pathogenesis. One of the key regulators of endothelial function is endothelial nitric oxide synthase (eNOS), encoded by the NOS3 gene. The C-786T promoter polymorphism of NOS3 has been studied as a potential genetic determinant of nitric oxide (NO) bioavailability and vascular response. This review synthesizes current evidence on the association of the NOS3 C-786T polymorphism with DFS severity, ulcer development, healing outcomes, and risk stratification in diabetic patients. Overall, findings suggest that NOS3 C-786T polymorphism may influence endothelial NO synthesis, contribute to impaired microcirculation, and serve as a genetic marker for individualized prognostic assessment and therapeutic stratification in DFS.
