World's first gene-edited babies? Premature, dangerous and irresponsible
A scientist in China claims to have produced the world’s first genome-edited babies by altering their DNA to increase their resistance to HIV . Aside from the lack of verifiable evidence for this non peer-reviewed claim, this research is premature, dangerous and irresponsible. He Jiankui from the Southern University of Science and Technology in Shenzhen (which has reportedly since suspended him) said he edited the DNA of seven embryos being used for fertility treatment, so far resulting in the birth of one set of twin girls. He says he used the tool known as CRISPR to delete the embryos’ CCR5 gene (C-C motif chemokine receptor 5), mutations in which are linked to resistance to HIV infection . If true, this is a significant advance in genetic science, but there are some very serious problems with this news. First, the research has not yet been published in a peer-reviewed journal so we cannot be sure of the exact details of what has been done. Instead, the scientist made ...
