The replaced gene is not transmitted to the next generation . The disease like SCID [severe combined immuno deficiency ] Cystic fibrosis , Hacmophilia , cancer etc can be cured by somatic cell gene thrapy . Note : The first gene therapy experiment involved extraction of T-lymphocytes from the bone marrow of SCID patient . A healthy copy of ADA gene is introducded int these cells with the help of retrovirus as vector . These engineere cells are then injected into the bone marrow of the patient where those cells multiply . The altered cells would produce enough adenosine deaminase to relieve the disease symptoms . The lymphocytes have definite life span the disease cannot be cured permanantly . Repeated injections of modified lymphcytes about three month for the patient are needed to control the disease ....
