Shiite Muslims follow closely with 13 mutations. Skeletal changes that result from expansion of the bone marrow, including: Deformities of the long bones of the legs, Typical craniofacial changes (frontal bossing, malar prominence, depressed nasal bridge, tendency toward upslanted palpebral fissures, and hypertrophy of the maxillae, which tends to expose the upper teeth), In children, growth restriction and failure of sexual maturation, In adults, involvement of the heart (dilated cardiomyopathy), liver (fibrosis and cirrhosis), and endocrine glands (resulting in diabetes mellitus and insufficiency of the parathyroid, thyroid, pituitary, and, less commonly, adrenal glands), Chronic hepatitis (resulting from infection with the viruses that cause hepatitis B and hepatitis C), Cirrhosis (from iron overload and chronic hepatitis), Extramedullary masses of hyperplastic erythroid marrow, Thrombotic complications from iron accumulation and hypercoagulable state secondary to the lipid membrane composition of the abnormal red blood cells, Ophthalmologic and audiologic examinations, Complete cardiac evaluation, and evaluation of thyroid, endocrine pancreas, parathyroid, adrenal, and pituitary function, Liver ultrasound evaluation and determination of serum alpha-fetoprotein concentration in adults with hepatitis C and iron overload for early detection of hepatocarcinoma, Bone densitometry to assess for osteoporosis in adults, Monthly complete blood counts and tests for blood iron levels every three months, Yearly tests for heart function, liver function, and viral infections including hepatitis and HIV, Yearly tests to check for iron buildup in your liver, Regular checkups to make sure blood transfusions are working, Tests to match your tissues with a possible donor if a stem cell transplant is under consideration. ACD is also present in chronic infections, some types of cancer, and arthritis. Researchers are continuing to make significant progress that may one day result in more effective treatments and possibly a cure. They may be prone to severe anemia and many other health problems, including: For example, with beta thalassemia major in some developing countries, treatments that include long-term transfusion programs are not available. The more severe form of the disease is thalassemia major, also called Cooley's Anemia. Without enough hemoglobin, red blood cells do not produce normally. in several consecutive generations are affected. They may have mild anemia. This therapy takes time and can be mildly painful. a 50% chance of being an asymptomatic carrier. Iron overload occurs mainly from increased intestinal absorption of iron caused by a deficiency of hepcidin. This condition is called beta thalassemia trait or beta thalassemia minor and causes mild anemia. Thalassemia disebabkan oleh gen dominan Th, sedangkan alelnya menentukan sifat normal. Making more fetal hemoglobin might make up for the lack of healthy adult hemoglobin found in thalassemia patients. However, a child who inherits two thalassemia trait genes - one from each parent - will have the disease.

The other risk factor is ancestry. Both thalassemia major and thalassemia intermedia can cause more than just anemia. There are two main types of thalassemia; “alpha thalassemia” and “beta thalassemia,” and each has several variations. This causes a shortage of mature red blood cells which can lead to anemia or other related health problems. Thalassemia is a treatable disorder that can be well-managed with blood transfusions and chelation therapy. A person needs two genes (one from each parent) to make enough beta-globin protein.
