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.
