Scientists for the first time have tried editing a gene inside the body in a bold attempt to permanently change a person's DNA to try to cure a disease.If it's successful, it could give a major boost to the fledgling field of gene therapy.There also are gene therapies that don't involve editing DNA.Some others supply a new gene like a spare part, but can't control where it inserts in the DNA, possibly causing a new problem like cancer.Madeux, who now lives near Phoenix, is engaged to a nurse, Marcie Humphrey, whom he met 15 years ago in a study that tested this enzyme therapy at UCSF Benioff Children's Hospital Oakland, where the gene editing experiment took place.The therapy has three parts: The new gene and two zinc finger proteins.The fingers cut the DNA, allowing the new gene to slip in.Only 1 percent of liver cells would have to be corrected to successfully treat the disease, according to Madeux's physician and study leader, Dr. Paul Harmatz at the Oakland hospital.Another worry is that inserting a new gene might have unforeseen effects on other genes.Several patients later developed leukemia because the new gene inserted into a place in the native DNA where it unintentionally activated a cancer gene.
