Just ten years ago, questions about editing genomes of the next human generation were largely hypothetical. The prospect of erasing fatal or debilitating diseases was seen as a goal worth pursuing, even as some worried about the slippery slope of using this technology to create “designer babies.” Since then, the science has progressed rapidly. We now have a variety of tools that move these possibilities from theoretical to plausible. Based on his own research, as well as knowledge of the findings of others conducting stem cell research, Evan Y. Snyder, MD, PhD, FAAP will describe some of these tools and lead a discussion addressing key questions such as: Do we want to do this at all? If we are editing human genomes, then should this be done in vitro, in utero, or after birth? Are there some things we should not do? Who decides? Series: "Exploring Ethics" [Show ID: 32989]
