<unk>  is a type of iron overload disorder associated with deficiencies in transferrin receptor 2. It exhibits an autosomal recessive inheritance pattern. The first confirmed case was diagnosed in 1865 by French doctor Trousseau. Later in 1889, the German doctor von Recklinghausen indicated that the liver contains iron, and due to bleeding being considered to be the cause, he called the pigment<unk> ." In 1935, English doctor Sheldon's groundbreaking book titled,<unk> , reviewed<unk> 11 patient case reports and presented the idea that<unk>  was a congenital metabolic disorder. Hereditary<unk>  is a congenital disorder which affects the regulation of iron metabolism thus causing increased gut absorption of iron and a gradual build-up of pathologic iron deposits in the liver and other internal organs, joint capsules and the skin. The iron overload could potentially cause serious disease from the age of 40–50 years. In the final stages of the disease, the major symptoms include liver cirrhosis, diabetes and bronze-colored skin. There are four types of hereditary<unk>  which are classified depending on the age of onset and other factors such as genetic cause and mode of inheritance.
