title: Role of hemochromatosis genes in chronic hepatitis C.
abstract: OBJECTIVE
  Hereditary hemochromatosis is commonly associated with iron overload and hepatitis C virus (HCV). Association between hemochromatosis C282Y or H63D mutation has been observed, although not uniformly, and iron overload is also commonly found in chronic HCV hepatitis. This study explored the contribution of genetic hemochromatosis to iron accumulation in hepatitis C.
  
  
  METHODS
  Review of current literature.
  
  
  RESULTS
  The prevalence of increased serum iron stores in patients with HCV infection is 28% (patients having an elevated ferritin or transferrin saturation). Patients with elevated serum iron markers have more active chronic hepatitis with more liver fibrosis. In the opinion of the experts HFE mutations are not associated with a high hepatic iron content. No relation was detected between hepatic iron stores and HFE gene mutation. Significant iron deposition in the liver was uncommon and overall the quantity of iron that was detectable histologically and biochemically was unrelated to the grade and stage of HCV related liver injury. The mechanism by which liver iron accumulates in patients is unclear.
  
  
  CONCLUSIONS
  Carriage of HFE mutations does not have a role in the accumulation of iron or the liver disease in HCV. These findings do not support a role for iron depletion in patients with chronic HCV infection, including these with elevated serum studies.
