Genetic babies were born naturally in China


Administrators and medical experts have been disturbing their & # 39; The idea of ​​a Chinese scientist who used Crispr technology to create his first current pants in the world, a couple.

Crispr's approach is to create a & # 39; cutting DNA lines to deactivate or change positive cheeses.

In a YouTube video posted on Sunday, Jiankui at the University of Shenzhen Science and Technology said that babies were born – identified as Lulu and Nana "to protect their privacy" – a few weeks ago "as healthy as Anyone else babies. "

He has been active in a number of genetic engineering companies, including Direct Genomics, which raised 218 million yuan ($ 31.4 million) in April. He said the girls had an in vitro product but added some protein and guidance for "genetic surgeon" for their father's and sperman's eggs.

According to the available information, the children's father is HIV positive, and genetic reproduction was made to defeat CCR5 gene, which allows HIV to contaminate cells.

"When Lulu and Nana were just one cell, that surgery made the way where HIV was going to reveal people," he said.

But yesterday, the state committee of medical experts experts in Shenzhen opened up the "moral issues" surrounding the issue.

According to documents that were recorded before the clinical trial, the HarMoniCare Hospital for Women and Children in Shenzhen agreed the test. But the local media said the hospital refused to take part.

He did not return to an interview request.

The scientists' applications, which were presented this week in Hong Kong at the Second International Meeting of the Human Genome Conference, were not published in a specialized journal where they had studied a detailed subject with other scientists.

Some scientists warned that this left many questions without answer, and others warned about the behavioral impact of his work, which is lawful in China but was banned in the United States, the United Kingdom, and many other countries. Over a hundred scientists and Chinese scientists put their name to a statement yesterday to explain the test as "crazy."

Joyce Harper, a professor of humanitarian organization at London University College, called Mr He, said "too fast, dangerous and irresponsible".

Dianne Nicol, director of the Center for Law and Genetics at Tasmania University, said gene re-registration to future generations would be "always tough for society."

"The future generations are not [por não terem nascido ainda]"she said," so we are allowed by the parents. "

Professor Nicol also warned that the dangers of genetic editing "are largely incredible."

"Although there is [técnica] Crispr is considered more reliable when you insert it into cell, you trust that it will go to the right place in the genome and do the right thing. But there is always a danger when you're putting something in cell, that it can go to the wrong part of the genome or that it can not affect it we are not aware of. "

Dusko Ilic, a music scientist at King & College London, also has many other ways to avoid HIV contamination.
