Type 1 hemochromatosis is one of the most common genetic disorders in the United States, affecting about 1 million people. It most often affects people of Northern European descent. The other types of hemochromatosis are considered rare and have been studied in only a small number of families worldwide.

Can you have hemochromatosis without the gene?

Haemochromatosis that is unrelated to mutations in the HFE gene are collectively referred to as non-HFE haemochromatosis. Non-HFE haemochromatosis occurs in populations world wide and makes up a larger proportion of HH cases in areas where the C282Y mutation is less common, such as Southern Europe[3] and Asia[4].

Are there primary and secondary forms of hemochromatosis?

Hemochromatosis can be classified as (a) primary, when it originates from a genetic disturbance that promotes the increase of iron absorption, or (b) secondary, when it relates to chronic diseases or to multiple transfusions.

Understanding Haemochromatosis

What are the 3 types of hemochromatosis?

Hemochromatosis has been separated into four distinct disorders – hereditary (classic) hemochromatosis, also known as HFE-related hemochromatosis or hemochromatosis type I, hemochromatosis type 2 (juvenile hemochromatosis), hemochromatosis type 3, also known as TFR-related hemochromatosis; and hemochromatosis type 4, ...

What are the stages of hemochromatosis?

There are four main categories of pathophysiological mechanisms of HH that should be mentioned: (1) the increased absorption of dietary iron in the upper intestine, (2) decreased expression of the iron-regulatory hormone hepcidin, (3) the altered function of HFE protein, and (4) tissue injury and fibrogenesis induced ...

What is Type 2 hereditary hemochromatosis?

Hemochromatosis type 2 is a disease in which too much iron builds up in the body. This is also called iron overload. Accumulation of iron in the organs is toxic and can cause organ damage. While many organs can be affected, iron overload is especially likely to affect the liver, heart, and pancreas.

Is hemochromatosis an autoimmune disease?

This disorder is caused by mutations in the hemojuvelin or hepcidin genes. Neonatal hemochromatosis. In this severe disorder, iron builds up rapidly in the liver of the developing baby in the womb. It is thought to be an autoimmune disease, in which the body attacks itself.

What does a hematologist do for hemochromatosis?

Treatments for hemochromatosis include therapeutic phlebotomy (fleh-BOT-o-me), iron chelation (ke-LAY-shun) therapy, dietary changes, and treatment for complications. The goals of treating hemochromatosis include: Reducing the amount of iron in your body to normal levels.

Does hemochromatosis affect your teeth?

Genetic haemochromatosis (GH) is responsible for iron overload. Increased transferrin saturation (TSAT) has been associated with severe periodontitis, which is a chronic inflammatory disease affecting tissues surrounding the teeth and is related to dysbiosis of the subgingival microbiota.

Can you drink coffee with hemochromatosis?

Both tea and coffee contain polyphenolic substances called tannins, also known as tannic acid. The tannins in tea and coffee inhibit iron absorption. This makes these two popular beverages a great addition to your diet if you have hemochromatosis.

Does hemochromatosis affect sleep?

Many patients also have periodic limb movements in sleep (PLMS), and they may complain of insomnia and/or hypersomnia. Hereditary haemochromatosis is an autosomal recessive disease of iron metabolism in which increased intestinal absorption of iron leads to iron deposition in multiple organs.

Can you reverse hemochromatosis?

There's currently no cure for haemochromatosis, but there are treatments that can reduce the amount of iron in your body. This can help relieve some of the symptoms and reduce the risk of damage to organs such as the heart, liver and pancreas.

When is phlebotomy needed for hemochromatosis?

Hemochromatosis. Although phlebotomy does not clinically improve hemochromatosis, it can prevent complications in patients with symptoms or organ damage. Continuous phlebotomy is recommended until the patient's serum ferritin levels are ≤50 ng/mL and their transferrin saturation is <50%.

What is dangerously high ferritin levels?

Many laboratories consider serum ferritin levels greater than 200 ng/mL in women and greater than 300 ng/mL in men to be abnormal.
