Brief description Thalassaemia is the most common inherited single gene disorder affecting haemoglobin synthesis in red blood cells. It mainly affects people of Mediterranean, Middle Eastern, African, South East Asian, Chinese, and Indian origin. However, large numbers of thalassaemia patients are found nowadays in Australia and other developed countries, due to large population movements in the twentieth century. Approximately 300,000 severely affected children are born each year with thalassaemia and various other abnormalities of haemoglobin synthesis. If untreated, most thalassaemia patients will die within the first few years of life. The vast majority of thalassaemia patients depend on regular blood transfusions every two to three weeks, and on nightly infusions of an iron chelator (a drug for removing excess iron from the blood). These procedures place considerable burden on thalassaemia patients, their families and society, and expose them to blood transmitted infections. The only curative treatment for thalassaemia is bone marrow transplantation from a matching donor. However, the vast majority of patients do not have matching donors and thus the only prospect for them to receive such therapy is to replace in their bone marrow cells a copy of the normal set of genes for the synthesis of haemoglobin. The studies in this proposal are therefore designed to test gene therapy protocols on bone marrow stem cells derived from thalassaemia patients. A normal set of globin genes will be delivered to the bone marrow stem cells via non-viral delivery systems and examined for function in an immunodeficient mouse strain that can accept human bone marrow. This research may enable bone marrow transplantation to be applied for the therapy of most patients with thalassaemia, while it may also have a major impact on therapeutic approaches for other haematological anomalies.
