      factor TherapyGene Therapy is the insertion of a broker or factors into cells in order to provide a new rank of instructions to those cells. Gene insertion can be used to set an inherited inherited defect which is causing disorder, to counter or remunerate the effects of a genetic mutation, or even to program a cell for an tout ensemble new function or property. Genes are represent of molecules of deoxyribonucleic acid, or DNA (see Nucleic Acids), and are usually located in the nucleus of cells. The instructions that direct the development of an organism are encoded within the genes. near diseases such as cystic fibrosis are caused by an inherited genetic defect. Other diseases are caused by a miscoding of a gene so that the instructions it contains are disrupted or changed. Genetic miscoding occurs when the DNA in a cell is being duplicated during cell growth and division (somatic mutation) and is commonplace when a cell becomes cancerous. Clini cal use of gene therapy began on family line 14, 1990, at the National Institute of Health in Bethesda, Maryland, when a four-year-old daughter received gene therapy treatment for adenosine deaminase (adenosine deaminase) deficiency, an ordinarily fatal inherited disease of the immune system. Because of this genetic defect she was susceptible to recurrent life-threatening infections. Gene therapy for this patient involved using a genetically modified virus to carry a convening ADA gene into her immune cells. The inserted ADA gene then programmed the cells to produce the missing ADA enzyme, which led to normal immune function in those cells. This treatment temporarily helped her to develop subway to infection. Gene therapy may eventually provide effective treatment for many a(prenominal) diseases that currently have no cure. These include inherited disorders such as cystic fibrosis, muscular dystrophy, and juvenile diabetes. In addition, gene therapy can as well be used to tre at many disorders that are not inherited, since gene insertion can also program a cell for an entirely new function. Several new therapies for non-genetic disorders are currently being tested.
