Mediterranean anemia; Cooley anemia Homozygous form : Occurs when both alleles have thalassemia mutations. This is a severe microcytic, hypochromic anemia. Untreated, it causes anemia, splenomegaly and severe bone deformities. It progresses to death before age Treatment consists of periodic blood transfusion ; splenectomy for splenomegaly and chelation of transfusion-related iron overload. As with about half of all hereditary diseases, [18] an inherited mutation damages the assembly of the messenger-type RNA mRNA that is transcribed from a chromosome.

Lately, he was among the leading scientists in the clinical validation of novel oral chelators and diagnostic assessment of cardiac iron overload. Blood analysis shows reduced Hb levels 50 12 Differential diagnosis is usually simple but may include genetic sideroblastic anemias, congenital dyserythropoietic anemias, and other conditions with high levels of HbF such as juvenile myelomonocytic leukemia and aplastic anemias; see these terms.
