British scientists have tested an "amazing" test that has been said to have created the world's first genetic infants in China.
Dr He Jiankui said that he did a couple capable of being taken with HIV by preventing the CCR5 gene to allow him to; dead virus getting into human cells.
He says that he did this in two daughters, called Nana and Lulu, who was born in China a few weeks ago, although the research was not published or independently proved.
Doing this in illegal living babies in many countries, including the UK, where researchers' scientists and scientists have "really inconsistent, informal and inaccurate" scientists, related to "Russian genetic roulette ".
People without protection of CCR5 gene from HIV can only be more vulnerable to other viruses, including hepatitis B and the West Nile virus, as well as flu vaccination.
Experts say genealogy generation also puts infants at a greater risk of bad birth and cancer.
Dr He, from the University of Southern Science and Technology in Shenzhen, was engaged in the recruitment of HIV-positive men and their partners for the treatment of fruit, and Providing protection to the children from the virus. A father who passes HIV has a chance of zero when his mother is not tied.
Proper cure was given to the couples, with a CRISPR-Cas9 breeding breed thrown into your ovine with sperm. This will work as a magnificent scissor for & # 39; surrender & output of the CCR5 gene; remove protein to bring HIV into cells.
The Doctor said that 16 out of 22 of the exercise were prepared, and 11 were used in six IVF attempts before a woman grew pregnant with her twins.
Dr He, who appeared before a non-international conference in Hong Kong, was described as "amazing" by Professor Julian Savulescu, director of the Oxford Uehiro Center for Practical Studies at Oxford University.
He said: "It is against a decimals of consensus and ethical guidance on the protection of people who participate in research. In many other parts of the world this would be illegal , who may be punished by the prison.
"These healthy babies are used as genetic gig pigs. This is a Russian generation species."
Dr Dusko Ilic, from the life sciences and medicine traditions at King's College London, said: "These people should be tackling crime – they tried to make children's lives without any reason to do.
"Technology is not ready to generate a perfect gene and … it can cause birth reasons, from spina bifida to learning disabilities, and can create genetic diseases that we have never heard."
The fear of generating a gene is that the CRISPR-Cas9, which is made up of circulation molecules and a "scissors" protein for cutting DNA, can nerve it on the # 39; part is wrong, causing the risk of other illnesses by generating genetic movements.
However, Dr. Heill's team asked for cells to be removed from the causes that came after them, and the babies when they were born, showed that the generations worked safely.
