Beta-thalassemia major is a serious hereditary hemolytic anemia which does great harm to human being.It is a monogenic disease characterised by a reduced synthesis of beta-globin chains,which dues to the Doint mutation or deletion of beta-globin gene and its control region.It not only decreases the hemoglobin level,but breaks the balance of alpha/beta synthesis ratio.The major cellular pathogenetic mechanisms in beta thalassemia are based primarily on the deleterious effects produced by the accumulation of the excess alpha globin chain.These excess alpha-globin chains cannot form stable tetrameric structure and deposit in erythroid cells.They cause large ineffective erythropoiesis on their own,accelerate red cells destruction,and lead to hemolysis.

地中海贫血是一种对人类健康危害严重的遗传性溶血性贫血病，是因β-珠蛋白基因及其调控序列的点突变或缺失致使β-珠蛋白肽链合成减少或完全停止，这不仅使患者血红蛋白水平降低，而且使原来在数量上与之持平的α-珠蛋白肽链相对过剩，这些相对过剩的游离α-珠蛋白肽链并不能形成稳定的四聚体，它们沉积在红细胞中导致了大量无效红细胞生成和红细胞寿命缩短，引起了严重的溶血性贫血。
