Hemochromatosis 2011

Summary

The example disease causes the example syndrome.

Hemochromatosis is a hereditary autosomal recessiv genetic disorder caused by a mutation of the HFE-Gen. It was first describted by Armand Trousseau in 1865 in a report about diabetes.

Phenotype

Hemochromatosis causes different symptoms. Some of them are listed below.

• decoloration/darkening of skin (also known as bronzening)
• weakness
• fatigue
• heart failure
• diabetis
• arthritis (iron in joints)
• loss of weight
• loss of body hair
• loss of sexual energy
• liver cirrhosis

HEF-Gene

The HFE-Gen alleviate the binding of transferrin which is the carrier protein for iron in the blood cyclus. With a mutated HFE-Gen, the intestines interpret a strong transferrin signal as an deficient in iron. Therefore the cells start to import iron, which leads to an iron overload.

Mutations

Current knowledge about mutations associated with the disease. - Separate into disease causing and neutral mutations. -- These sequence pages will be the starting point for collecting prediction results and result discussions.
