The current chapter in the debate about the societal and political implications of human germline editing took off nearly four years ago, in response to a laboratory experiment in which researchers in China used CRISPR technology on nonviable human embryos. In March 2015, an article titled “Don’t Edit the Human Germline,” coauthored by scientists and others working on somatic cell genome editing and associated with the Alliance for Regenerative Medicine, appeared in the “Comment” section of Nature. A week later, Science published a “Perspective” commentary coauthored by another group, most of them scientists convened by CRISPR codiscoverer Jennifer Doudna, under the title “A prudent path forward for genomic engineering and germline genetic modification.”

The first article described the “tenuous” therapeutic benefit, and the likely serious risks (including risks to future generations), of germline editing. The authors concluded that this technology was “dangerous and ethically unacceptable,” in part because “permitting even unambiguously therapeutic interventions could start us down a path towards non-therapeutic genetic enhancement.” They further suggested that “a voluntary moratorium in the scientific community could be an effective way to discourage human germline modification.”

In contrast, the second article stressed “the promise of curing genetic disease.” While it concluded that “there was an urgent need for open discussion of the merits and risks of human genome modification by a broad cohort of scientists, clinicians, social scientists, the general public, and relevant public entities and interest groups,” it asserted that the goal of such discussion would be to “enable pathways to responsible uses of this technology, if any, to be identified.” The authors recognized that it would be premature to move forward with human germline genome editing, but studiously avoided any use of the term moratorium.
