GM twins are born in 2018



According to Chinese trained instructor Standfor, infants are immune to HIV. The news has generated criticism and raised controversy.


Chinese researcher said he had in vitro fertilization with & # 39; genetically modified birth with twins that are resistant to the AIDS virus, notice that raised ethical criticism for acts deemed "dangerous" and "irresponsible".

He Jiankui, a professor at the University & # 39; Shenzhen in southern China, announced a video on YouTube announcing the birth a few weeks ago & # 39; twin whose DNA has been modified to be resistant to the AIDS virus. He stated that the father is HIV positive.

The researcher, trained at Stanford in the United States and conduct specialized laboratory in the genome in & # 39; Shenzja, explained that he used the Crispr technique Cas9, called "genetic scissors", which allows to remove and replace parts unwanted genome, as Leave in computer defect.

The baby, called "Lula" and "Nana", born from in vitro fertilization & # 39; modified embryo before being implanted in the uterus of & # 39; mother. "After injecting sperm & # 39; men in eggs, embrijott Crispr injected the protein-Cas9 charged with modifying a gene to protect girls from future HIV infection", explained Jiankui.

This self-proclaimed medical event has not been verified by & # 39; independently. The results of the Chinese team has not been published in & # 39; scientific journal.

"The announcement of & # 39; these results in & # 39; a video on YouTube is very problematic scientific practice", thought Nicholas Evans, professor of philosophy at the University & # 39; Lowell Massachusetts, in the United States, working on issues bijoetiċi.

"This removes processes & # 39; control, which support many scientific advances, such as peer assessment," he added, questioned by AFP.

If you announce or not, the issue raised "serious ethical concerns", says Sarah Chan, a & # 39; University & # 39; Edinburgh, cited by the Science Media Center. "The such requests, apparently to seek maximum deliberately & # 39; controversies (…), are irresponsible", he added.

His announcement comes on the eve of conference & # 39; & # 39 worldwide experts; genomes f & # 39; Hong Kong during which the researcher will present its findings in detail.
