Novel protocells or xenobiological organisms, as well as gene editing of higher animals, may have novel biosafety hazards that affect their risk assessment. As of 2018, most laboratory biosafety guidance is based on preventing exposure to existing rather than new pathogens. [4]
Pioneer gene-editing scientists had warned in 2015 that "genome editing in human embryos using current technologies could have unpredictable effects on future generations. This makes it dangerous and ethically unacceptable. Such research could be exploited for non-therapeutic modifications."
The impact of human gene editing on resistance to HIV infection and other body functions in experimental infants remains controversial. The World Health Organization has issued three reports on the guidelines of human genome editing since 2019, [ 41 ] and the Chinese government has prepared regulations since May 2019. [ 42 ]
With this kind of genetic editing, scientists could inadvertently make a change to a patient’s DNA that is off-target, and the therapy could harm the patient.
These gene drives were originally engineered in January 2015 by Ethan Bier and Valentino Gantz; this editing was spurred by the discovery of CRISPR-Cas9. In late 2015, DARPA started to study approaches that could halt gene drives if they went out of control and threatened biological species.
He Jiankui, the Chinese scientist who sparked global outrage in 2018 when he revealed that he had created the first gene-edited children, has put forward a new proposal for modifying human embryos ...
