Gene therapy Summar

The concept of gene therapy was introduced in the late 1970s after the development of recombinant DNA technology. After the development of basic science and technology for gene transfer into patient's cells, the first gene therapy trial on humans was performed in 1990 by researchers at the National Institutes of Health Gene therapy is a medical therapeutic process involving the delivery of the gene into cells to treat diseases. It is an application of recombinant DNA technology in the field of medicine. The main aim of gene therapy is to cure a disease by providing the patient with a correct copy of the defective gene How did Gene therapy begin? On September 14, 1990, W. French Anderson and his colleagues at the NIH performed the first approved gene therapy procedure on a four-year-old girl born with severe combined immunodeficiency (SCID) (Anderson, 1990) The disadvantage of gene therapy is that, like any other medical procedure, it may not work. The experimental nature of these therapies means that the costs can be high to have them performed and many health insurance policies will not cover it because of the potential of failure. Here are some additional pros and cons of gene therapy to think.
