乙型地中海贫血(简称地贫)是一种先天性溶血性贫血,主要是由病人血红蛋白的基因(遗传基本物质)发生变异而遗传到下一代后引起的疾病。正常人的血红蛋白是由两对多肽链构成的,一对是甲肽链(简称甲链),另一对主要是乙链和少量的丙链与丁链。甲链和乙链合成为主要的成人血红蛋白(称 HbA,占成人血红蛋白总量的97%),
Thalassemia Thalassemia (Thalassemia) is a form of congenital hemolytic anemia, which is a disease inherited from the patient’s hemoglobin gene (genetic material) that is mutated to the next generation. Normal hemoglobin is composed of two pairs of polypeptide chain, a pair of peptide chain (referred to as a chain), the other is mainly a small chain of ethyl and a small amount of C and D chain. A and B chain synthesis of the major adult hemoglobin (called HbA, accounting for 97% of adult hemoglobin)
