Abstract

Hereditary hemochromatosis is the most common inherited single-gene disorder in people of northern European descent. It is characterized by increased intestinal absorption of iron, with deposition of the iron in multiple organs. Previously, the classic description was combined diabetes mellitus, cutaneous hyperpigmentation and cirrhosis. Increasingly, however, hereditary hemochromatosis is being diagnosed at an earlier, less symptomatic stage. The diagnosis is based on a combination of clinical, laboratory and pathologic findings, including elevated serum transferrin saturation. Life expectancy is usually normal if phlebotomy is initiated before the development of cirrhosis or diabetes mellitus. Hereditary hemochromatosis is associated with mutations in the HFE gene. Between 60 and 93 percent of patients with the disorder are homozygous for a mutation designated C282Y. The HFE gene test is useful in confirming the diagnosis of hereditary hemochromatosis, screening adult family members of patients with HFE mutations and resolving ambiguities concerning iron overload.
