Multiple Choice

Which findings support the diagnosis of hereditary hemochromatosis and associated liver risk?

Hereditary hemochromatosis causes iron overload because mutations in the HFE gene lead to increased intestinal iron absorption. The key lab pattern is a high transferrin saturation (the percent of transferrin bound with iron) along with elevated ferritin, reflecting increased body iron stores. The presence of HFE gene mutations provides a genetic confirmation, making this combination the strongest support for the diagnosis and for the associated liver risk due to iron deposition in hepatocytes, which can progress to fibrosis, cirrhosis, or hepatocellular carcinoma. Low transferrin saturation and ferritin would argue against iron overload; normal iron studies or negative liver imaging likewise do not fit this picture, since iron overload can occur with abnormal iron indices even if imaging is not yet revealing.
