HONG KONG (AP) – Chinese researcher who
He said he helped create the world's first genetically engineered baby, today announced that a second pregnancy could develop.
Jianquan, a 34-year-old associate professor in the southern city of Shenzhen, discovered a possible pregnancy in his first public announcements of his controversial work at an international conference in Hong Kong.
He says that it changes the DNA
Two twins born at the beginning of the month to try to make them immune to the AIDS virus. The scientific community condemned the experiment, and universities and government groups are investigating the situation.
The second possible pregnancy is very early in life, and more time is needed to confirm whether it will continue, he said.
After his speech, leading scholars said that there are now more reasons than ever to worry and ask more questions than answers. The conference director describes the experiment as "irresponsible," noting that it was proof that the scientific community was not able to self-regulate and avoided the first effort to change the DNA.
Replacing a DNS before or at the time of a concept is a very controversial issue, because changes can inherit and may damage other genes. In some countries, including in the United States, this practice is prohibited, with the exception of laboratory studies.
I defended my choice of HIV, rather than the fatal congenital disease, to try genetic editing, and insisted that girls could benefit.
"They need this protection because the vaccine is not available," said a researcher. But scientists did not confirm their approach.
"This is really unacceptable progress," said Jennifer Douda, a University of California-based Berkeley University student and one of the inventors of the CRISPR gene-editing tool. He said that she was using. "I am grateful that she appeared today, but I do not think that we have heard answers, we need to understand what this motivation is."
Doudna is paid by the Howard Hughes Medical Institute, which also supports the Associated Press's Department of Medicine and Science.
There is currently no independent confirmation of His statement, which has not yet published its research in any scientific journal, in which it can be verified by experts. At the conference, he declined to answer many questions, including who paid for work, how he ensured that participants understood the potential risks and benefits and why he kept his work secret until it was completed.
Regulators rushed to condemn the experiments as unethical and non-scientific.
The Chinese National Health Commission ordered local officials in Guangdong Province to investigate his actions and the center in which he works, and the South Korean University of Science and Technology also studied what was happening.
