Anemia, Mediterranean . Hemoglobin F Disease . Thalassemia Major . Thalassemia Minor . A disorder characterized by reduced synthesis of the beta chains of hemoglobin. There is retardation of hemoglobin A synthesis in the heterozygous form (thalassemia minor), which is asymptomatic, while in the homozygous form (thalassemia major, Cooley's anemia, Mediterranean anemia, erythroblastic anemia), which can result in severe complications and even death, hemoglobin A synthesis is absent. . 1.00
Hemoglobins. Eryhem . Ferrous Hemoglobin . Hemoglobin . Hemoglobin, Ferrous . The oxygen-carrying proteins of ERYTHROCYTES. They are found in all vertebrates and some invertebrates. The number of globin subunits in the hemoglobin quaternary structure differs between species. Structures range from monomeric to a variety of multimeric arrangements. . 0.43
Methemoglobinemia. Methemoglobinemias . The presence of methemoglobin in the blood, resulting in cyanosis. A small amount of methemoglobin is present in the blood normally, but injury or toxic agents convert a larger proportion of hemoglobin into methemoglobin, which does not function reversibly as an oxygen carrier. Methemoglobinemia may be due to a defect in the enzyme NADH methemoglobin reductase (an autosomal recessive trait) or to an abnormality in hemoglobin M (an autosomal dominant trait).

delta-Thalassemia. delta Thalassemia . delta-Thalassemias . A hereditary disorder characterized by reduced or absent DELTA-GLOBIN thus effecting the level of HEMOGLOBIN A2, a minor component of adult hemoglobin monitored in the diagnosis of BETA-THALASSEMIA. . 0.40
Hemoglobin M. A group of abnormal hemoglobins in which amino acid substitutions take place in either the alpha or beta chains but near the heme iron. This results in facilitated oxidation of the hemoglobin to yield excess methemoglobin which leads to cyanosis. . 0.39
Thalassemia. Thalassemias . A group of hereditary hemolytic anemias in which there is decreased synthesis of one or more hemoglobin polypeptide chains. There are several genetic types with clinical pictures ranging from barely detectable hematologic abnormality to severe and fatal anemia. . 0.39
