Abstract
This study discusses the ontological assumptions assumed in the bioethical debate about human genetic selection and gene editing. With a view to managing genetic disorders, different therapies have been employed clinically and experimentally, since the 1990s. Among the treatment strategies, we find embryo selection (by means of pre-implantation genetic diagnosis) and gene therapy (by means of gene editing). The development of these techniques raises discussions about their ethical implications. This article postulates that different conceptions of humanity can be identified in these discussions, grounding ethical positions regarding genome interventions. The article seeks to analyze these conceptions, following three steps. First, the biomedical context of genetic selection and gene editing is presented. Then, discussions on the ethical aspects of these interventions are highlighted. Finally, different conceptions of humanity grounding these discussions are identified and analyzed, considering the notion of distributive justice.
