Members belonging to the scientific community fear the misuse of this therapy leading to dangerous consequences.  People may try to insert the desired gene, for example, the gene for tallness, intelligence etc and play with the natural system. 

Any scientific development if not used in a righteous manner may lead to blunders and gene therapy is no exception. Almost all developments in medicine are associated with side effects similar to gene therapy. One should identify the factors which may lead to the setbacks in gene therapy like faulty vectors, lack of chances for clinical investigation etc. It is a wonderful technology which can eradicate large number of genetic disorders. Hence, instead of being skeptical, it is time to move ahead and accept this technology (Elias and Annas, N.D).
