The FDA sent a stern letter today to Dr. John Zhang, PhD, MD, the physician who last year created a genetically modified human embryo in the U.S. and then exported it to Mexico where he self-reported creating a genetically modified baby boy. While the genetically modified baby created in Mexico was reportedly seemingly OK, it’s not clear what kind of health issues he might face in the future and I haven’t seen much data on him. I believe his parents subsequently declined to have him participate …Read More

Until that data is released publicly we should all be cautious on this news. Apparently the clinic plans to present such data later. Assuming it is a 3-person IVF baby, which …Read More

Some scientists including myself have spoken out publicly about these risks, which include potentially disastrous developmental problems for the children produced via this method. However, others including a panel …Read More
