Just Say No to Editing Human Embryos for Reproduction

Over the last few decades, the international community has issued several bioethical guidelines and legally binding documents, ranging from UN Declarations to regional charters to national legislation, about editing the human germline–the DNA that is passed down to future generations. There was a broad consensus that modifications should be prohibited. But now that CRISPR-cas9 and related methods of gene editing are taking the world by storm, that stance is softening–and so far, no thorough public discussion has emerged.
There is broad agreement in the scientific and ethics community that germline gene editing must not be clinically applied unless safety concerns are resolved. Predicting that safety issues will indeed be minimized, the National Academy of Sciences issued a report this past February that sets up several procedural norms. These may serve as guidelines for future implementation of human embryo editing, among them that there are no “reasonable alternatives,” a condition that is left deliberately vague.
I regard the conditional embrace of germline gene editing as a grave mistake: It is a dramatic break with the previous idea of a ban, departing...

The U.S. Food and Drug Administration (FDA) is supposed to encourage effective medical advances while also ensuring that patients and research subjects are protected. This dual mandate demands tricky judgment calls that are made more difficult by outside pressures of several kinds, political, judicial, and especially commercial. This April story at Bloomberg examines one deeply troubling pattern of regulatory capture:

Uyghurs, a predominantly Muslim minority in China, are mainly located in the autonomous region of Xinjiang. The Chinese government has pursued an aggressive settlement policy in this region since 1949, with the percentage of Han Chinese in the region increasing from five to forty percent in the second half of the 20th century. Since 2014, the Uyghurs have been subject to persecution and re-education – various sources have estimated that at least one million...

Louise Perry’s recent article in The Spectator cautions against “The quiet return of eugenics,” a threat she locates in preimplantation genetic testing for polygenic disorders. The technology is billed as a way for parents undergoing IVF to select which embryo to implant based on information about each embryo’s genetic risk factors and traits. These reports, she says, give parents “a very full picture of the adult that embryo could become”––from their child’s risk of developing different diseases to their “likely...
