China has unveiled draft regulations on gene editing and other potentially risky biomedical technologies after a Chinese scientist’s claim of helping to create gene-edited babies roiled the global science community.
Under the proposed measures released this week, technology involving gene editing, gene transfer and gene regulation would be categorized as “high-risk” and managed by the health department of the State Council, China’s Cabinet.
The measures follow assertions in November from scientist He Jiankui that he altered the DNA of twin girls born that month using a powerful new tool. The technology, called CRISPRcas9, makes it possible to operate on DNA to supply a needed gene or disable one that’s causing problems.
The revelation that it may have been used to conceive children elicited widespread outcry over the procedure’s ethical implications.
Researchers said He’s actions exposed the twins to unknown health risks, possibly including a higher susceptibility to viral illnesses.
Gene editing for reproductive purposes is effectively banned in the U.S. and most of Europe. In China, ministerial guidelines prohibit research on embryos that “violates ethical or moral principles.” Ethical guidelines published in 2003 say that gene editing is permitted for research, but that the experimental embryo cannot be nurtured for more than 14 days.
