Definition of Gene Therapy

Gene therapy is the process in which the copy of the gene is introduced into the somatic cells. It can also be stated as an experimental technique in which the genes are modified in order to treat and prevent certain genetic disorders. Gene therapy is done in three ways.


First, the genes that are mutated and are causing disease are replaced by the healthy version of that gene. Second, the mutated gene that is functioning in an abnormal manner is inactivated or knocked out. Third, a new gene is being introduced into the body that helps the body in fighting the disease. It is currently being done only for such diseases either acquired or genetic which do not have any other treatment.
