A, Exon 2 wild-type and mutant sequences. Perhaps m.65177's dr has not published. It's my understanding that there is no harm in donating blood and is good for your body.I also believe that you can't have HH with only one gene. I wonder it there is a connection between hemochromatosis and elevated VLCFAs? In this case only one gene is required to set it off. I should add that my Very Long Chain Fatty Acids are elevated enough that I had genetic testing for carrier status of adrenoleukodystrophy but I’m clear. Always speak to your doctor before acting and in cases of emergency seek Scientists know very little about VLCFAs. severe iron overload related disease, however 60-80% will develop abnormal iron studies during their lifetime.7 If iron overload is present, lifelong venesection is required. The cause of this needs to be investigated properly and not just allocated to the haemochromatosis basket. He seemed to be asymptomatic before he was diagnosed. This test measures the amount of iron stored in your liver. The wild-type bases of the hot-spot mutations are underlined. Donald Turbiville, BS, Xiaotang Du, MD, Jacob Yo, BS, Bagi R Jana, MD, Jianli Dong, MD, PhD, Iron Overload in an HFE Heterozygous Carrier: A Case Report and Literature Review, Laboratory Medicine, Volume 50, Issue 2, April 2019, Pages 212–217, https://doi.org/10.1093/labmed/lmy065. Copyright © 2021 American Society for Clinical Pathology. patients with a H63D/H63D genotype with elevated ferritin). Blood tests for serum iron and either total iron binding capacity or transferrin are good screening tests. Diabetes. Infertility. There is a poster on this forum who has had to find out all about ferroportin herself and she says Canada (where she comes from) do not test for it. Increased levels of ferritin indicate that the iron level in your body is high. Our clinical information is certified to meet NHS England's Information Standard.Read more. If the patient has hemochromatosis, I would start a phlebotomy program to keep ferritin levels below 200 ng/mL and transferrin saturation below 40 to 50 percent. Generation of an induced pluripotent stem cell line (DHMCi006-A) from a patient with autosomal recessive polycystic kidney disease (ARPKD) carrying a compound heterozygous missense mutation in the fibrocystin encoding PKHD1 gene. Further testing such as this would be valuable in our patient. My son had glandular fever at age 18 which caused some damage to a lot of the organs that are affected by HH and this may have had an impact on his levels at such a young age. Blood ferritin levels usually are low in patients with iron deficiency anemia, and are high in patients with hemochromatosis and other conditions that cause an increase in body iron levels. Blood tests to measure iron and total iron binding capacity (TIBC) Blood tests to measure aspartate aminotransferase.

Examination of her head, eyes, neck, cardiovascular system, pulmonary system, abdomen, musculoskeletal system, and neurological system yielded no abnormal findings. Was initially told to donate monthly. How do doctors treat hemochromatosis? Oxford University Press is a department of the University of Oxford. Inheritance tends to follow an autosomal recessive pattern. Those with hemochromatosis will tend to be high in ALL THREE iron labs i.e. ", http://www.genetics.edu.au/publications-and-resources/facts-sheets/fact-sheet-47-hereditary-haemochromatosis, "Approximately 0.5-2% of people with one copy of the C282Y mutation and one copy of the H63D mutation will have iron overload ", http://www.clevelandclinicmeded.com/medicalpubs/diseasemanagement/hepatology/hemochromatosis/. It is like an afterthought. Is it possible that she could have HH.? Also, this case demonstrates that monitoring TS and SF values in C282Y carriers may be valuable because iron overload in such cases remains unpredictable due to the influence of many genetic and environmental factors. Posted These tests can detect the problem before symptoms appear. I am not sure what you are saying about compound heterozygous C282Y/H63D. If you are still having these symptoms almost 30 years of venesections (and supposedly de-ironed) then something else is wrong which is causing your elevated ferritin. Donatella Baronciani, MD Cagliari, Italy She has a reported history of hemochromatosis, hypertension, and osteoporosis, with no history of diabetes or hypopituitarism. So in my opinion it is due to normal variations or genetic predisposition and not likely due to hemochromatosis. If I am a carrier with elevated levels does that mean I have hemochromatosis? This article focus on the general principles of hemochromatosis, as well as effects of iron accumulation in the liver, the most frequently affected organ. I invite you to continue your journey of knowledge. Serum ferritin is also markedly elevated. Haematologica, 96(4), 507–514. Check out previous haemochromatosis posts to find her posts regarding this disorder and you might find some similarities (or not!). Thanks again for sharing your knowledge of this condition as many Drs are not familiar with the condition which makes this forum helpful when you don't seem to get the answers you need from the Dr. Because her SF level had increased recently, she was restarted on phlebotomy procedures once a month, with the goal of reaching an SF level of 50 to 100 µg per L in the future. So the outcome will be very interesting to a lot of people. Thank you so much for your links regarding this issue. Blood tests to measure ferritin. We examined HEF C282Y, H63D, and S65C mutations, from specimens donated by the patient, using PyroMark HFE pyrosequencing assay, according to manufacturer-provided instructions (QIAGEN, N. V.). The doctor tested me for hemochromatosis, told me I was a carrier and referred me back to my regular physician for monitoring. Testing of HFE codon C282Y, H63D, and S65C mutations showed heterozygous C282Y. It also won't hurt you to donate blood at least every three months and you will be doing something good for other people. Hemochromatosis may not be recognized until later in life. You might be doing yourself a favour by pushing for an appropriate diagnosis for your health issues. It would seem that your gastroenterologist does not understand genetic haemochromatosis. diabetes mellitus. Men are different because they don't naturally lose blood as we do while having periods so are predominently worse. SF, serum ferritin;TS, transferrin saturation; TIBC, total iron-binding capacity; ALT, alanine transaminase; AST, aspartate aminotransferase; H, levels higher than normal range. You will need to undergo thyroid function tests to make sure whether there are something wrong with your thyroid. Treatment of hemochromatosis can improve symptoms and prevent complications. Transferrin is your short-term iron storage. We examined the literature for cases similar to that of our patient, to illuminate her case. However, an elevated serum ferritin level is not diagnostic for hereditary hemochromatosis; the positive predictive value for detection of C282Y homozygotes ranges from 1.6 to 17.6 percent.17 Did you read the "Iron Overload" page? m.65177 is right in advising you to seek official medical advice rather than just from forums. The serum ferritin concentration is a sensitive measure of iron overload, but it is also an acute-phase reactant and is therefore elevated in a variety of infectious and inflammatory conditions in . Just be relaxed. They are called 'carriers' because they carry the defective gene and can pass it on to their children. respect of any healthcare matters. High Ferritin If the blood test reveals excessively high levels of ferritin in your blood, this means that the iron stored in your liver is leaking into the blood. I had no further treatment for five years, but this summer I did the 23 and me test which does show I’m a C282y carrier. Gilbert's syndrome is a common genetic disorder caused by a deficiency of the enzyme UDP-glucuronyl transferase, which leads to an increase in the levels of unconjugated bilirubin. There is an increased prevalence of mild iron overload in compound heterozygotes (C282Y/H63D), and some C282Y heterozygotes may also carry an unidentified second mutation. Not all individuals with a genetic predisposition to HH will go on to develop high serum ferritin or iron overload. The iron is 'free' because it is not bound tightly to carrier proteins which would otherwise prevent it from damaging cells. Try eliminating all (well, most) sugars and starchy foods from your diet. I am just looking for any information. I have HH with homoygous C282Y genes (inherited from both parents) and my kids are carriers only having one gene. The patient, to date, had been tested for HFE gene mutation, and the results were C282Y heterozygous. Patients and Methods: We recently investigated four C282Y carrier patients with unusually high iron parameters, including increased levels of serum ferritin (SF), high transferrin saturation (TS) and high iron liver content measured by MRI. That might explain why you still have these problems and high ferritin levels after 30 years of regular phlebotomies because it is difficult to treat. Patients may present with mild jaundice, particularly at times of intercurrent illness. Agarose gel electrophoresis was performed to check the quantity and quality of the PCR products. Haemochromatosis is characterised by the excessive absorption of iron. Most patients are asymptomatic and are diagnosed when elevated serum iron levels are noted on a routine chemistry screening panel or when screening is performed because a relative is diagnosed with hemochromatosis.

Causes Without Iron Overload. Herein, we describe a 64-year-old Caucasian woman with a reported history of hemochromatosis. Iron overload disorders, including hemochromatosis, cause the body to absorb too much iron. She donates blood regularly. "Carriers of the hemochromatosis gene often have iron overload, It has been common for physicians to tell patients with mild elevations in serum ferritin levels that they may be carriers of the hemochromatosis gene. If your ferritin level is currently 300 then you have not been de-ironed and kept there. Drs seem to be pouncing on haemochromatosis as a cause because it is easier for them, rather than conduct a search for the real diagnosis. The recommendation to see a gastro dr should be followed through as it may provide the answer to her health issues. A database of people with hemochromatosis in France (well, the southern half it seems) is kept in Montpellier.
