There are five types of hereditary hemochromatosis: type 1, 2 (2A, 2B), 3, 4 [9] and 5, [10] all caused by mutated genes. Hereditary hemochromatosis type 1 is the most frequent, and uniquely related to the HFE gene. It is most common among those of Northern European ancestry, in particular those of Celtic descent. [11]
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 ...
Hemosiderin collects throughout the body in hemochromatosis. Hemosiderin deposition in the liver is a common feature of hemochromatosis and is the cause of liver failure in the disease. Selective iron deposition in the beta cells of pancreatic islets leads to diabetes [ 4 ] [ 2 ] due to the distribution of transferrin receptor on the beta cells ...
Juvenile hemochromatosis, also known as hemochromatosis type 2, is a rare form of hereditary hemochromatosis, which emerges in young individuals, typically between 15 and 30 years of age, but occasionally later.
People with conditions like hemochromatosis (iron overload), gout, or vitamin A toxicity should avoid or limit their consumption, and pregnant individuals should talk to their doctor first.
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.
