In 2015, Chinese scientists have successfully edited the genome of human in the laboratory. Then about the creation of genetically modified people to talk all the international community and some countries have even completely banned such experiments. But China has continued to work in this direction and recently he Cisangkuy from South science and technology University in Shenzhen said to the public that the world has witnessed the birth of the first genetically modified people.
As reported by MIT Technology Review, a team of scientists from South science and technology University for such an important event specifically selected a couple of people who were planning the procedure of in vitro fertilization (IVF). With the editor of the genome of CRISPR-Cas9, scientists have modified the gene CCR5, which should make the offspring resistant to smallpox, cholera and HIV.
Despite claims of success, the story still does not add up to the whole picture. Announced the success he Cisangkuy still did not give comments about certain aspects. For example about whether childbirth physiological. However, available data suggests that all genetic tests were performed during the first 24 weeks of pregnancy. The Associated Press reports that the world’s first genetically modified humans have become two twin girls that have received the names Nana and Lulu. However, the available information is not sufficient in order to talk about the fact that the modification was successful and the health of children threatens nothing.
In addition, some researchers have questions and edit the CCR5 gene. It is believed that people without working copies of a gene are immune or highly resistant to HIV infection. However, this applies to those who initially did not have this gene. In this case we are talking about simulating this on live embryos, and in fact a genetic mutation. Yes, removing the CCR5 gene to create resistance to HIV can be quite a significant reason, but scientists say that there are easier and less costly, means of HIV prevention.
As with all controversial situations, the global scientific community is divided. While some are optimistic about the future, others are trying to find potential danger in the creation of genetically modified people
“The technology is in principle ready for use on human embryos. But we must understand that the changes are inherited by future generations and may eventually affect the entire gene pool. We’ve never done anything that will change the genes of the human race, and we never did anything that will have consequences that will last for generations.” said David Baltimore, a biologist and former President of the California Institute of Technology.
