Scientists have expressed anger and Chinese genetic claims that xenophobic genes have been published by genes of great birth, governments have ordered experimental research.
After a genetic scientist, He Jiankui, used the Chris Rip-Cas9 gene-editing tool, according to a video released on YouTube, they began to put a specific gene into two embryos in their mother's womb.
The genomes changed to disable a gene called CCR5, the pathway used by the HIV virus to enter cells.
Some scientists, the International Gender Genome Editors, began on Tuesday in Hong Kong, said scientists announced their work following scientific protocols, without publishing their findings in the peer-reviewed journal. Others referred to the aforementioned ethical problems to improve humans better.
Qiu Renzong, a professor of bioethics and emeritus at the Beijing Academy of Social Sciences Academy, said he was determined to work outside the scientific protocols established by Chinese science.
"Obviously, it's not ethical," Qiu said, publicly criticizing her work before attending more than hundreds of people. Qiu said the university, in the South of Science and Technology in Shenzhen, requested an experiment. This led to Stanford education. He discovered a private hospital in the academic application of research. "It's clear that it's a scam," said Qiu. "Maybe he made a form and people signed it."
The Chinese National Health Commission has mandated investigating and verifying officials. In addition, the Hospital and Family Planning Committee, when scientists worked, said that they were studying ethical questions.
Feng Zhang, a molecular biologist at the McGovern Institute of the Brain Research Institute of Massachusetts, and one of the founders of Crispr Technology, published results for the scientific community to study their work.
"I do not think I managed to manage it in a transparent manner, especially since I first read it when I read it in the reading newspaper," said Zhang. "And I think transparency is very important especially for new experimental treatments."
If the reactions are true, the twins will change the DNA in any child, scientists say, they would create many ethical and medical problems.
"It is something that will have consequences in our lives," said Mohammed Ghaly, Professor of Islam, and Professor of Biomedical Ethics at Hamad Bin Khalifa University, in Doha, Qatar. "We ended with the great ethical questions … the decision about these little girls was not something they did, but someone else's. Their changes will continue in the future generations.
"To make decisions that affect our society, our lives and our grandchildren and our grandchildren over the long term?"
Some scientists accused you and their work without knowing more details. "Basically, nothing is done [genome] It changes between humans against the embryo, "said Eben Kirksey, an associate professor of anthropology at Deakin University in Victoria, Australia.
But Kirksey raised difficult ethical questions. "It threatens to create a genetically modified elite … it can not get sick but it goes through others."
