Spanish scientists warned that the announcement that genetically modified babies had been obtained was not published in any scientific journal and had not been evaluated either; "You can not play God this way," said José Alcamí, of the Carlos III Health Institute.
"This subject – in reference to the Chinese researcher who directs the investigation on He Jiankui – is a criminal," he said. Efe Alcamí, for whom the announcement may cause "a lot of harm to science"

The team of the hen claims to have created the world's first genetically modified baby using twin twins CRISPR / Cas9 to make them resistant to diseases such as HIV.
Alcamí pointed out that this announcement "will generate a kind of warning against scientists who are working well" with this "wonderful" technique: this gentleman, comparing his model, "attacked a bank and now, they we will all treat them as thieves. "
Ethical Codes
And, according to the scientist, it would appear that the eq Some Chinese researchers have ignored all the ethical codes: no one knows how the experiment has been conducted – the University of Shenzhen in which they work has no record of the study – and if it is confirmed that a human embryo manipulation has been performed, that will create a move against.
For Alcamí, the CRISPR technique "is fascinating and the people who use it know that it is possible to edit the genome and modify cells in culture or even mice – always with the necessary permissions for each research project must conform –
"But we also know that this can introduce mutations out of the specific area, so the system is not validated for use with humans. "
" It is therefore not excluded that these girls have mutations introduced into other genes that are not seen now but that could pose a problem for them in the future ", according to the scientist, who said that this technique still presents some unpredictability
The Chinese team based its experiments on the "deactivation" of the CCR5 gene, which HIV uses as a gateway in the immune system, but, according to Alcamí, the dice activation of this gene also has consequences because it facilitates other infections. for viruses like West Nile fever.
"We can not play gods in this way," lamented Alcamí, who reminded that everything related to the use of this technique is already well controlled by the ethics committees. . and governed by the Biomedical Research Act.
