Quizplus · Accepted Answer

Gene therapy has had success in treating genetic disorders involving bone marrow cells, such as severe combined immunodeficiency disease (SCID) and beta-thalassemia. However, it is not a widely accepted procedure, and there have been challenges and limitations in its use. It does not involve replacement of a defective allele in sex cells, as that would be germline gene therapy and is currently controversial and not widely practiced.
