Thalassemia is a genetically heterogeneous disorder caused by germline mutations that decrease the synthesis of either α-globin or β-globin, leading to anemia, tissue hypoxia and red cell hemolysis related to the imbalance in globin chain synthesis. Thalassemia is endemic in the Mediterranean basin (thalassa means “sea” in Greek) as well as the Middle East, tropical Africa, the Indian subcontinent, and Asia, and in aggregate is among the most common inherited disorders of humans.
