Alpha thalassaemia
Overview Thalassaemia refers to a group of disorders characterised by reduced or absent globin chain production. Thalassaemia is one of the haemoglobinopathies, which refers to a group of autosomal recessive inherited disorders that affect the globin chains that form the protein component of haemoglobin. Haemoglobinopathies Haemglobinopathies can be broadly divided into two types: Haemoglobin variants: mutant forms of haemoglobin that affect the structure. Sickle cell disease is most well recognised. Thalassaemia: reduced or absent globin chain production due to underlying mutations. Thalassaemia Thalassaemia can be further divided depending on the type of globin chain affected: Alpha thalassaemia: reduced or absent production of
