The discovery and development of the CRISPR/Cas9 system has provided a second opportunity for gene therapy to recover from its stigma and prove to be valuable therapeutic strategy. Following the treatment, Misztal no longer had spontaneous bleeding episodes. Researchers had hoped that . Initially the therapy appeared somewhat successful: most of the 10 children who were treated started producing functional T cells—an important component of a working immune system. mutations in a single gene can be vastly different depending on the precise location of the DNA change. Eating, moving, and breathing become difficult. Gene therapy replaces a faulty gene or adds a new gene in an attempt to cure disease or improve your body's ability to fight disease. Successes represent a variety of approaches—different vectors, different target cell populations, and both in vivo and ex vivo approaches—to treating a variety of disorders. Viral gene therapy: successes and failures. Gene therapy holds great promise for treating cancer, inherited disorders, and other diseases.
