What is Human Gene Transfer (a.k.a. “Gene Therapy”)?
Human gene transfer is the process of transferring genetic material (DNA or RNA) into a person. DNA may be transferred as “naked” DNA, encapsulated DNA, or DNA within another organism, such as a virus. Use of retroviral vectors in humans also constitutes human gene transfer when the virus contains enzymes that result in a DNA copy of the RNA genome. Human gene transfer is experimental and is being studied to see whether it could treat certain health problems by compensating for defective genes, producing a potentially therapeutic substance, or triggering the immune system to fight disease. Human gene transfer may help improve genetic disorders, particularly those conditions that result from inborn errors in a single gene (for example, sickle cell anemia, hemophilia, and cystic fibrosis). It may also hold promise for diseases with more complex origins, like cancer and heart disease. Gene transfer is also being studied as a possible treatment for certain infectious diseases, such as AIDS
