Gene therapy is an experimental technique that uses genes to treat or prevent disease This technique may allow doctors to treat a disorder by inserting a gene into a patients cells instead of using drugs or surgery Researchers are testing several approaches to gene therapy including Replacing a mutated gene that causes disease with a healthy copy of the geneInactivating or knocking out a mutated gene that is functioning improperlyIntroducing a new gene into the body to help fight a disease Gene therapy is used to correct defective genes in order to cure a disease or help your body better fight diseaseReplacing mutated genes Some cells become diseased because certain genes work incorrectly or no longer work at all Replacing the defective genes may help treat certain diseases For instance a gene called p53 normally prevents tumor growth Several types of cancer have been linked to problems with the p53 gene If doctors could replace the defective p53 gene that might trigger the cancer cells to dieFixing mutated genes Mutated genes that cause disease could be turned off so that they no longer promote disease
