CRISPR Ethics: Moral Considerations for Applications of a Powerful Tool

With the emergence of CRISPR technology, targeted editing of a wide variety of genomes is no longer an abstract hypothetical, but occurs regularly. As application areas of CRISPR are exceeding beyond research and biomedical therapies, new and existing ethical concerns abound throughout the global community about the appropriate scope of the systems' use. Here we review fundamental ethical issues including the following: 1) the extent to which CRISPR use should be permitted; 2) access to CRISPR applications; 3) whether a regulatory framework(s) for clinical research involving human subjects might accommodate all types of human genome editing, including editing of the germline; and 4) whether international regulations governing inappropriate CRISPR utilization should be crafted and publicized. We conclude that moral decision making should evolve as the science of genomic engineering advances and hold that it would be reasonable for national and supranational legislatures to consider evidence-based regulation of certain CRISPR applications for the betterment of human health and progress.

Do CRISPR Germline Ethics Statements Cut It?

The extraordinary wave of genomic-engineering innovation, driven by CRISPR-Cas9, has sparked worldwide scientific and ethical uncertainty. Great concern has arisen across the globe about whether heritable genome editing should be permissible in humans-that is, whether it is morally acceptable to modify genomic material such that the "edit" is transferable to future generations. Here I examine 61 ethics statements released by the international community within the past 3 years about this controversial issue and consider the statements' overarching positions and limitations. Despite their inability to fully address all important considerations, many of the statements may advance debate and national and international law and public policy.
