Hemochromatosis type 4 is a hereditary iron overload disorder that affects ferroportin, an iron transport protein needed to export iron from cells into circulation. [1] Although the disease is rare, it is found throughout the world and affects people from various ethnic groups.
Standard diagnostic measures for haemochromatosis, transferrin saturation and ferritin tests, are not a part of routine medical testing. Screening for haemochromatosis is recommended if the patient has a parent, child, or sibling with the disease. [62] Routine screening of the general population for hereditary haemochromatosis is generally not ...
The presence of hemochromatosis may be discovered incidentally on blood testing, or a diagnosis suspected based on symptoms may be supported or ruled out by blood testing. Elevated serum ferritin , an indicator of blood iron levels, and transferrin saturation , which is involved with absorption of iron from the gut, are very common.
Iron overload (also known as haemochromatosis or hemochromatosis) is the abnormal and increased accumulation of total iron in the body, leading to organ damage. [1] The primary mechanism of organ damage is oxidative stress, as elevated intracellular iron levels increase free radical formation via the Fenton reaction.
Treatment for hemochromatosis type 3 may include reducing iron levels by removing blood (phlebotomy), iron chelation therapy, diet changes, and treatment for complications of the disease. The purpose of the treatment is to reduce the amount of iron in the body to normal levels, prevent or delay organ damage from excess iron, and maintain normal ...

This finding helps in the early diagnosis of hereditary hemochromatosis, especially while serum ferritin still remains low. The retained iron in hereditary hemochromatosis is primarily deposited in parenchymal cells, with reticuloendothelial cell accumulation occurring very late in the disease.
