gene therapy Gene Therapy is the insertion of a gene or genes into cells in order to provide a new set of instructions to those cells. Gene insertion can be used to correct an inherited genetic defect which is causing disease, to counter or correct the effects of a genetic mutation, or even to program a cell for an entirely new function or property...	2 / 409

Does searching for a cure demean the lives of individuals presently affected by disabilities? ? Is somatic gene therapy (which is done in the adult cells of persons known to have the disease) more or less ethical than germline gene therapy (which is done in egg and sperm cells and prevents the trait from being passed on to further generations)? In cases of somatic gene therapy, the procedure may have to be repeated in future generations...	1 / 233
