Term Definition
A protein component of the red blood cell pigment haemoglobin essential for oxygen-transport. Absence of beta-globin in the blood, caused by inheritance of two mutated copies of the beta-globin gene, causes thalassaemia, a common blood disorder. It is also relevant in sickle cell anemia: A person with the sickle cell trait inherits one normal beta-globin gene (hemoglobin A) and one defective gene (hemoglobin S).
