TherapyGene therapy may one day be used to treat, cure, or prevent a variety of genetic disorders. In gene therapy, a type of virus known as a retrovirus is used to replace a defective gene in cells with a new, healthy gene. Scientists insert the healthy gene into the ribonucleic acid (RNA) of the retroviruses. These retroviruses are mixed with cells taken from a patient and cultured in a laboratory. The retroviruses insert the healthy gene in to the deoxyribonucleic acid (DNA) of the cells. The cells with the new, healthy gene are then injected back into the patient.© 1993-2003 Microsoft Corporation. All rights reserved.
