Debate about so - called germline editing of eggs, sperm and embryos has been going on for decades, but it has come to a head in recent years with the development of a powerful new gene - editing technology called Crispr - Cas9 that can make extremely precise edits to DNA and which was used by the Chinese team and would be used by the British team.

Its participants released a statement concluding that it would be «irresponsible» for researchers to move forward with clinical human germline editing until its risks and benefits were better known, and there was «broad societal consensus» on its use.

A recent report on genome editing from the National Academies did not call for a moratorium on research into germline editing, arguing that it might one day be a way for some parents to have healthy, biological children, such as when both mother and father carry genetic mutations that cause severe diseases.

Still, the panel says that strict government oversight should be in place to prevent anyone from using germline editing for other purposes, such as to give a baby desirable traits.

Some researchers are pleased with the report, saying it is consistent with previous conclusions that safely altering the DNA of human eggs, sperm, or early embryos — known as germline editing — to create a baby could be possible eventually.

As Funk notes, both surveys «show that public views about gene editing vary depending on whether the techniques would involve germline editing or testing on human embryos» and that there are «wide differences» based on religious beliefs.

But whether germline editing is the best way to prevent the transmission of genetic diseases occupied much of the summit discussions.

«This type of research should prove valuable for understanding the many complex issues around germline editing,» adds Daley.

He says that the manuscript went through two rounds of review over eight months — twice as long as is normal for the journal — and that he urged the researchers to discuss the ethical issues surrounding germline editing in the paper.

And on September 14, Britain's Royal Society and the Chinese Academy of Sciences announced that they would join forces with the US National Academy of Sciences and the US National Academy of Medicine to host a summit in December on germline editing (genetic changes to embryos, sperm and eggs).

«It's noteworthy that... they've been able to make some of these claims,» offers Michael Werner, executive director of the Alliance for Regenerative Medicine in Washington, D.C., who argued in a 2015 Nature commentary that ethical and safety issues should put germline editing research off limits.

Potential off - target effects in muscle, as well as unwanted germline editing, must be rigorously examined over a long period of time.

Such tinkering with embryo DNA, called germline editing, is controversial because of fears that the technology will be used to create so - called designer babies.

A recent report on genome - editing from the National Academies did not call for a moratorium on research into germline editing, arguing that it might one day be a way for some parents to have healthy, biological children, such as when both mother and father carry genetic mutations that cause severe diseases.

It's really a pretty dramatic shift from the existing and widespread agreement globally that human germline editing should be prohibited,» says Marcy Darnovsky, executive director of the Center for Genetics and Society in Berkeley, California.

Because changing the DNA of an early embryo results in changes to cells that will eventually produce sperm and eggs, if the embryo is born and grows to adulthood, any children he or she has will inherit the genetic alteration, which is called germline editing.

Yet the group — 12 biologists, physicians, and bioethicists — did not flatly rule out future use of such «germline editing,» in which the DNA changes would be passed down generations.

Ishii worries about countries such as the United States: there, germline editing is not banned but requires government approval, but such restrictions have a history of being circumvented, as in the case of unproven stem - cell treatments.

The report — issued by dozens of experts convened by the National Academy of Sciences and the National Academy of Medicine — says so - called germline editing, in which genetic changes are passed to future generations, should happen only when there's no «reasonable alternative» treatment.

«Germline editing» — genetic modification of human cells, including embryos, eggs and sperm, that can be passed to future generations — has been controversial.

The controversy led to the 2015 NAS summit, where organizers concluded that «it would be irresponsible to proceed with any clinical use of germline editing» without more research on safety and societal discussion.
