Hemoglobinopathy types
WebWithin this subset, there are two overlapping groups: the hemoglobinopathies and the thalassemias. Hemoglobinopathies typically have at least one amino acid substitution leading to synthesis of a variant globin chain. Thalassemias, on the other hand, involve perturbation of the rate of globin chain synthesis (1). WebHemoglobin consists of 4 globin polypeptide chains. Adult hemoglobin A consists of 2 alpha chains and 2 beta chains (α2β2). The α chain comprises 141 amino acids; the β chain …
