Patients with various conditions lacking a suitable donor for transplant have been treated with retroviral vectors and a gene-addition strategy. Initial promising results were shadowed by the occurrence of malignancies in some of these patients. Current trials, developed in the last decade, employ safer viral vectors to overcome the risk of genotoxicity and have led to improved clinical outcomes. This review reflects the progresses made in specific disorders including adenosine deaminase deficiency, X-linked severe combined immunodeficiency, chronic granulomatous disease and Wiskott-Aldrich syndrome. The success of these studies suggests that gene therapy has the potential to become a standard therapeutic option in the care of patients with these disorders. ID - discovery1564448 ER -
