Genome Editing in Medicine: A Scoping Review of Ethical, Bioethical, and Medico-Legal Implications

Abstract Genome editing, prominently led by the revolutionary CRISPR-Cas9 technology, is a powerful tool with significant applications in diverse fields, particularly in medicine and agriculture. It empowers scientists with the ability to effect precise genetic modifications, thereby potentially paving the way for advanced treatments for genetic disorders such as Huntington’s disease, hemophilia, and cystic fibrosis. Yet, the significant capabilities of this technology also brings to the fore a myriad of intricate bioethical, legal, and regulatory dilemmas. In light of these complexities, this article endeavors to conduct a comprehensive scoping review of the existing literature on the most significant ethical implications emanating from genome editing. In conducting this review, we utilized the power of software tools like EndNote and Rayyan to aid in the systematic and thorough review of the literature. EndNote, a reference management software, was instrumental in organizing and managing the references and bibliographies, while Rayyan, a web application designed for managing and screening records for systematic and scoping reviews, proved crucial in the import and management of text records for the review.The review identified as main aspects of ethical, bioethical and medico-legal interest the exacerbation of social inequalities, safety concerns such as off-target mutations and immunological risks, ecological and evolutionary implications, and challenges to human dignity. It highlights the necessity for equitable access, rigorous regulation, and public engagement to address these issues responsibly.The ultimate objective of this article is to underscore the importance of an informed and inclusive dialogue regarding genome editing. Such dialogue is pivotal for fostering responsible innovation in this rapidly advancing field, ensuring that scientific progress aligns with ethical considerations. By presenting a comprehensive examination of the ethical implications of genome editing, we aim to contribute to this ongoing dialogue and promote a balanced and nuanced understanding of this impactful technology.
