Genetic Haemochromatosis :: essays research papers

Genetic haemochromatosis is a disorder, which causes exhort build up everyplace time. Usually an adult has about 4 grams of iron in their body but with this disorder the amount of iron in the body is much higher, with the entireness amount of iron in the body reaching up to 20 to 40 grams if untreated. In Australia, haemochromatosis affects 1 in 200-300 people but it is most earthy in Australians whose ancestry is from Northern Europe or the United Kingdom.If haemochromatosis is left untreated, it leads to conditions such asCirrhosis of the liverCardiomyopathyDiabetesTo prevent these problems from developing, early diagnosis and treatment is needed. The treatment for this disorder is done by regularly extracting blood, from the same main vein, as the one thats used for when a person donates blood. By doing this regularly, it reduces the high levels of iron in the blood so that it doesnt get stored in various organs.People who are affected by haemochromatosis may stage no sympt oms at all. The symptoms of this disorder are more likely to develop in men aged between 40 and 60 years white-haired and at a later age for women, although the disorder can be diagnosed much earlier. For this disorder, symptoms vary according to the organs involved. In the early years there may be no symptoms at all except for a healthy skin colouring that seems like a tan. Although early symptoms that occur in some people areWeaknessWeight LossLack of interest or concernSexual drivePain in the girdMuscle TendernessCramps in the legsSymptoms may occur earlier in men though because women lose blood during menstruation and childbirth causing the iron levels in the body to reduce.THE CAUSES OF HEREDITARY HAEMOCHROMATOSISThe component most commonly involved in hereditary haemochromatosis is called the HFE gene. On the short arm of chromosome number 6 is where this gene is located. The HFE gene codes the protein that regulates iron absorption. When the HFE gene is faulty the message from the gene is also faulty causing the iron storage that regulates itself to fail. Two mutations, called C282Y and H63D, have been identified in the HFE gene. It appears to cause most of the cases of hereditary haemochromatosis.Being born with two faulty HFE gene copies does not actually have to mean that a person ordain definitely develop HH, it just means that they are more easily affected by hereditary haemochromatosis then others.
