What are the 4 types of thalassemia?

The four main types of thalassemia are alpha thalassemia, beta thalassemia, delta-beta thalassemia, and gamma-delta-beta thalassemia. These types of thalassemia are characterized by deficiencies or abnormalities in the production of specific globin chains that make up hemoglobin. Alpha thalassemia involves a reduced production of alpha globin chains, while beta thalassemia involves a reduced production of beta globin chains. Delta-beta thalassemia and gamma-delta-beta thalassemia involve abnormalities in the production of delta and gamma chains along with beta chains. The severity of thalassemia can vary depending on the number of affected globin chains and their specific genetic mutations. A comprehensive evaluation by a healthcare professional is necessary to diagnose and classify the specific type of thalassemia.
