It depends on a few things. It depends significantly on the method of silencing genes, and then there's the silencing of the genes themselves. Since gene therapy potentially is permanent, a high level of risk potential is present. Since Benitec's technology is viral vector delivered, we worry about immune response, for one. I'm no scientist, but your question has the potential to be a loaded one. Lol. Maybe someone else can expound better than I can.
