Aim & Background: The mechanism of steatosis in Hepatitis C virus infection is multifactorial; therefore, it is complex and unclear. The aim of this study was to investigate the effects of methylentetrahydrofolate reductase (MTHFR) gene polymorphisms on the course of chronic hepatitis C virus infection and the development of steatosis due to hepatitis C virus. Methods: This study included 109 patients with chronic hepatitis C virus infection. Necroinflammatory activity, degrees of fibrosis and

Polymerase chain reaction-restriction fragment length polymorphism was used to determine MTHFR C677T and A1298C polymorphisms. Results: Fibrosis was correlated with age (r = 0.336, p = 0.002), platelet (r = −0.448, p < 0.0001), ALT (r = 0.241, p = 0.026), AST (r = 0.361) and GGT (r = 0.224, p = 0.039). Steatosis was only correlated with fibrosis. MTHFR C677T and A1298C polymorphisms did not have a significant effect on the degree of steatosis (p = 0.857, p = 0.202 respectively). There was a relation between MTHFR C677T and the degree of fibrosis but not A1298C (p = 0.014, p = 0.187 respectively). Conclusion: We found that MTHFR C677T polymorphism contributed to the development of fibrosis in patients with chronic hepatitis C virus infection.
