Project Summary The breakneck pace of development towards potential uses of germline gene editing (GGE) in medicine raises some very crucial ethical questions. Though much research still needs to be done before GGE will be safe for use on humans, the technology has progressed very rapidly over the past few years. Among the most pressing of the ethical issues raised by GGE are those concerning human subjects research. Future clinical trials will confront novel ethical conundrums that are difficult to resolve given current guidelines.
