Abstract
Traditional distinctions between treatment and enhancement goals for human genome editing (HGE) have animated oversight considerations, yet these categories have been complicated by the addition of prevention as a possible target for HGE applications. To assess the role these three categories might play in continued HGE governance efforts, we report on interviews with genome editing scientists and governance group members. While some accepted traditional distinctions between treatment and enhancement and rejected the latter as unacceptable, others argued that the concept of enhancement is largely irrelevant or not as morally problematic as suggested. Others described how preventive goals for HGE create gray zones where prevention and enhancement may be difficult to distinguish, which may stymie uses of HGE. We conclude by discussing the governance implications of these various understandings of treatment, prevention, and enhancement as HGE research moves beyond the treatment of serious disease to embrace longer range preventive goals.
