Iron and HFE or TfR1 mutations as comorbid factors for development and progression of chronic hepatitis C.

Background/aims: Recent evidence implicates iron as a comorbid factor for development of non-hemochromatotic liver diseases. Mutations or polymorphisms in the HFE gene or the TfR1 gene may influence the accumulation of iron in the liver or other tissues or may influence chronic viral hepatitis apart from effects on iron homeostasis. The aim of this study was to assess the role of hepatic iron, HFE and TfR1 variations on development and progression of chronic hepatitis C infection.
