He Jiankui was sentence to three years in prison as well as a $430,000 fine for editing embryos of impregnated women in in experiments. Jiankui claims he was attempting to edit the embryos disable the gene CCR5, which encodes a protein that allows HIV to enter cells. His goal was to replicate a mutation found in 10% of Europeans to protect them from infection. Jiankui may have inadvertently caused other dangerous mutations but nothing can be know until follow-up research is done on the girls. The Chinese health ministry will be in charge of gathering information in said follow-ups.
The backlash from this unregulated experiment can potentially hover many more regulatory measures over the genome editing community. Many of the nations with gene editing regulatory practice have highly restrictive or intermediate measures in place, while Mexico and China have comparatively permissive guidelines. The primary argument against gene editing in human is who decides when is it absolutely necessary and no longer potentially more harmful. Much of the modern world is under this notion so the regulations will remain restrictive. However many scientists argue for looser restrictions so that more research can be done to finely tune gene editing to a point of viability
