GENE THERAPY

method of treating disease (esp. genetic disorders) in which normal genes are introduced into the body in order to replace defective or absent genes (Medicine)

Gene therapy is the insertion of genes into an individual's cells and tissues to treat a disease, and hereditary diseases in which a defective mutant allele is replaced with a functional one. Although the technology is still in its infancy, it has been used with some success. Antisense therapy is not strictly a form of gene therapy, but is a genetically-mediated therapy and is often considered together with other methods.
