Thalassemia is an inherited autosomal recessive blood disease that originated in the Mediterranean region. In thalassemia the genetic defect, which could be either mutation or deletion, results in reduced rate of synthesis or no synthesis of one of the globin chains that make up hemoglobin. This can cause the formation of abnormal hemoglobin molecules, thus causing anemia, the characteristic presenting symptom of the thalassemias. Thalassemia is a quantitative problem of too few globins synthesized, whereas sickle-cell disease is a qualitative problem of synthesis of an incorrectly functioning globin...
