A hereditary form of hemolytic anemia resulting from a defective synthesis of hemoglobin: thalassemia major is the homozygous state accompanied by clinical illness, and thalassemia minor is the heterozygous state and may not have evident clinical manifestations. Also known as Mediterranean anemia.



(also thalassanemia), a familial hemolytic anemia, first detected in 1925 among inhabitants of the Mediterranean region. Thalassemia is caused by disturbances in hemoglobin synthesis.
