Hemochromatosis is a disease characterized by excess absorption and storage of iron in the body’s tissues. Eventually, a build-up of iron impairs liver, heart and pancreatic function and leads to the development of arthritis, diabetes, cirrhosis and heart failure. These abnormalities are accompanied by a bronzed pigmentation of the skin.

Haemochromatosis is an inherited condition where iron levels in the body slowly build up over many years. This build-up of iron, known as iron overload, can cause unpleasant symptoms. If it is not treated, this can damage parts of the body such as the liver, joints, pancreas and heart.

C282Y Heterozygote . Individuals who are heterozygous for C282Y may have mild symptoms of hemochromatosis such as lethargy, joint pain, and weakness but are unlikely to develop the disease. Haemochromatosis type 1; Other names: HFE hereditary haemochromatosis HFE-related hereditary haemochromatosis: Iron accumulation demonstrated by Prussian blue staining in a patient with homozygous genetic haemochromatosis (microscopy, 10x magnified): Parts of normal pink tissue are scarcely present. Four genes are responsible: hepcidin and hemojuvelin are the genes involved in type 2 or juvenile hemochromatosis, transferrin receptor 2 is involved in type 3 hemochromatosis and ferroportin 1 is mutated in type 4, the atypical dominant form of primary iron overload (Best Pract Res Clin Haematol 2005;18:235, Semin Liver Dis 2005;25:450) Haemochromatosis is an inherited condition where iron levels in the body slowly build up over many years. This build-up of iron, known as iron overload, can cause unpleasant symptoms. Type I hemochromatosis is caused by defects (mutations) in the HFE gene. HFE has many purposes, but one important role is that it helps to control the amount of iron that is absorbed from food.

Heterozygous hemochromatosis

Heterozygous: Having one copy of the abnormal HFE gene, for example C282Y or H63D – also known as a ‘carrier’. Hereditary hemochromatosis is a genetic disorder that can cause severe liver disease and other health problems. Early diagnosis and treatment is critical to prevent complications from the disorder. If you have a family health history of hemochromatosis, talk to your doctor about testing for hereditary hemochromatosis.

Hemochromatosis has 7,664 members. This is a support group for people whose lives are affected by Heamochromatosis. I hope you share your experiences and if you have any information that you would like to share with others then please post it here. This group is not run/administrated by anyone with a medical background.

Haemochromatosis is an autosomal-recessive disorder. Common presenting features include fatigue and arthralgias.

av M Elmberg · 2010 · Citerat av 4 — Genetic hemochromatosis (GH) is an autosomal recessive disease caused by a C282Y Heterozygous mutation is common (1/5-1/15), and is associated with

My mom and one brother and I have been DNA tested, His brother 61 years old has a compound heterozygous C282Y/H63D hemochromatosis managed with phlebotomy treatment every 2 weeks up to a ferritin to 56 ng/ml during a phase of attack (the initial serum ferritin 756 ng/ml), his sister and mother have diabetes mellitus. Carriers (also known as heterozygotes) have one altered HFE gene and one normal HFE gene and are generally not affected by iron overload. Iron overload 8 Dec 2007 H63D has also been identified as a point mutation that predisposes to iron overload to a lesser degree. Among whites, about 90% of patients Hereditary hemochromatosis (HH) is a general term for several rare genetic gene mutation known as “H63D” (compound heterozygotes for C282Y/H63D). pound heterozygous state or C282Y/H63D), H63D mutations have been Abbreviations used in this paper: HH, hereditary hemochromatosis;. HIC, hepatic iron Since several alleles affect iron absorption, another possibility is you could have two different heterozygous mutations simultaneously.

It is rare for people who are compound heterozygous to load iron in amounts that cause organ damage. People with two copies of H63D, one from each parent, are considered to have a very low risk of having genetic haemochromatosis. diagnosis for most patients.

What??? I know it sounds complicated.
