Protection zone for the genetic material : gene researchers are calling for a five-year ban for interventions in the human germ line

"We are calling for a worldwide Moratorium on all clinical applications of germ – line the Change in heritable DNA (in sperm, egg cells or embryos), in order to make genetically modified children procedures." The and internationally effective regulations for the enforcement of – call geneticist from seven countries. Among them is prof Emmanuelle Charpentier from the Berlin Max-Planck-Institute for infection biology, was instrumental in the invention, the Gene-scissors "CRISPR/Cas9", which has made such interventions are only feasible.

Not a permanent ban on

in the second sentence of the call, published in the journal "Nature", not the researchers, however, clear that they are in favour of a permanent ban, but for an environment in which the countries commit themselves "voluntarily", no germ-line interventions allow, "unless certain conditions are met". Nevertheless, germ-line intervention should remain "of any kind" – first of all, for a "specified period" is forbidden, such as five years. To establish the get time, to discuss the technical, scientific, medical, social, ethical, and moral aspects, as well as an international set of rules.

Only then, Nations germline interventions allow, but only if three conditions were met: The Public should be timely informed in advance and the pros and cons extensively and internationally will be discussed. Then had to carefully and transparently to ensure that the application is justified. And in each country a "broad social consensus must be" germ-line interventions in General and in the specific case of Mr. Here not unanimity or majority was meant to emphasize the researchers. Social consensus would need to be assessed by the national authorities, such as governments assess the views of their citizens in other complex social issues politically. "Nations, be sure to choose different paths", - stated in the paper, but you should act with the necessary respect for the opinions of the rest of humanity, because this question relates to the entire species.

International body to watch over the human germ line

Therefore, should be discussions and information about germline therapies of an international institution coordinated, which could be at the world health organization, and the should be learning both from science as well as experts for social and ethical questions. It was "essential," groups with the perspectives of the disadvantaged other than the participate in medical or scientific in the discussion on the clinical use of germline therapy: people with disabilities, patients and their families, or financially, and historically marginalized groups of the civil society.

New to the moratorium proposal, the appeal, does not alter the germ line for the time being, is not. The recommended by researchers as early as 2015, after the first international "Genome Editing Summit" in Washington. "Irresponsible" was it, with the clinical application of germ line therapy to move forward before impact, and security are clarified and there is a broad consensus in society. Now, after the second Summit, call the researchers to more binding international and national regulations. Because, apparently, the Appeals were not enough to stop the Chinese, He Jiankui, the change in the end of November 2018 with the Gene-scissors the genetic material of two children – supposedly for life to protect against HIV infection. Researchers knew of the experiments, to take measures to stop him.

Medical necessity of germ line interventions, "extremely rare"

the mid-1970s, worked the self-regulation of researchers even better. At the time, the few geneticist that there was, in California's Asilomar Standards agreed, including the US geneticist Paul Berg, who also signed the current moratorium appeal. Today, there are a large number of the biophysicist He Jiankui hardly anybody knew.

His attempt, children with a Mutation, protection against HIV will get infection, shows that when germline therapy is not only to Correct the ill make of genetic defects. "Extremely rare" cases in which the parents can come only with a germ line therapy, healthy children, according to the signatories. He Jiankui healed with his procedure is not a disease, but trying to eliminate with an uncertain outcome - vulnerability to Aids.

The urge for "improvement" of the people

probabilities for infections to minimize, reduce the risk of cancer, improving memory – to imagine some "enhancement" (enhancement) of the genome. However, the "attempt to alter the species on the Basis of our current Knowledge", is hubris, the researchers write. In this respect, the required rule should be "particularly adventurous plans for a transformation of the human species obstacles in the way."

However, the legal expert Jochen Taupitz, University of Heidelberg, the "political-practical implementation estimates" of these claims as "very difficult". Governments in countries in which there is no legally binding prohibition of germ-line intervention, could not simply pronounce a ban.

to establish How difficult international rules, the 2015 adopted but it is hardly the reputation of the Unesco belonged to a Moratorium. Also, the German ethics Council calls for 2017, the international political process for binding Standards for germ-line interventions. Therefore, the current appeal made by the researchers was to welcome the group, but "a Moratorium should be not only an agreement to waive the clinical application of a genetic germline modification", writes Christiane Woopen, chair of the European ethics Council. It must also provide "consequences for the case that individual scientists rely on such an agreement." This is lacking in the current proposal. (smc)
