Thalassemia is a blood disorder that is caused by DNA mutations in cells that are responsible for producing haemoglobin. This leads to a reduction in the number and ability of the red blood cells to carry oxygen throughout the body and can cause sufferers to feel symptoms such as fatigue.
Alpha Thalassemia- Alpha-thalassemia arises due to insufficient synthesis of alpha-haemoglobin chains and an excess of beta chains. Beta Thalassemia- Beta-thalassemia occurs due to insufficient synthesis of beta-haemoglobin chains and an excess of alpha chains. Regular blood transfusions are the only treatment available to patients with thalassemia.
