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. . 1.00
Hemoglobin A2. A2, Hemoglobin . An adult hemoglobin component normally present in hemolysates from human erythrocytes in concentrations of about 3%. The hemoglobin is composed of two alpha chains and two delta chains. The percentage of HbA2 varies in some hematologic disorders, but is about double in beta-thalassemia. . 0.57
delta-Globins. delta Globin . delta Globins . delta-Globin . A member of the beta-globin family. In humans, delta-globin is encoded in the beta-globin gene cluster located on CHROMOSOME 11. Two delta-globin chains along with two alpha-globin chains form HEMOGLOBIN A2 which makes up about 3% of the HEMOGLOBIN in adults. . 0.52
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. . 0.51
Hemoglobinuria. The presence of free HEMOGLOBIN in the URINE, indicating hemolysis of ERYTHROCYTES within the vascular system. After saturating the hemoglobin-binding proteins (HAPTOGLOBINS), free hemoglobin begins to appear in the urine. . 0.44
