What are the 3 types of hemochromatosis?
Hemochromatosis has been separated into four distinct disorders – hereditary (classic) hemochromatosis, also known as HFE-related hemochromatosis; hemochromatosis type 2 (juvenile hemochromatosis); hemochromatosis type 3, also known as TFR2-related hemochromatosis; and hemochromatosis type 4, also known as ferroportin …
What hemochromatosis means?

What are the four types of hemochromatosis?
Hemochromatosis type 1 is caused by pathogenic variants in the HFE gene. Hemochromatosis type 2 is caused by pathogenic variants in the HFE2 (HJV) or HAMP genes. Hemochromatosis type 3 is caused by pathogenic variants in the TFR2 gene. Hemochromatosis type 4 is caused by pathogenic variants in the SLC40A1 gene.
Is hemochromatosis a Viking disease?
The C282Y mutation is assumed to have arisen in Europe more than 4,000 years ago (30). Its geographical distribution coincides with Viking travel routes, which suggests that the mutation spread with the Vikings.

Who was the first person to describe haemochromatosis?
Rudolf Virchow (1821 – 1902), in his autopsies on organs with internal bleeding, had described a yellow-brown pigment referred to as haematin as early as in 1847 (7). The pigment could be stained Berlin blue and thus contained iron.
What does hereditary haemochromatosis do to the body?
Hereditary haemochromatosis 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 (1).
