…we now know that one of the twins also has some cells where one copy of the gene wasn’t edited at all , meaning this twin has thus taken on the risks of gene editing without the supposed benefit of HIV protection.
I’ll summarize another fact. He was only able to test 80-90% of the genome to make sure it hadn’t thrown those changes around other areas outside of CCR5. Because of the mosaic nature of embryonic cells, this “sampling” is not remotely close to the 80-90% of claimed (something he conveniently left out). Not even sure if he only did genomic (as in only actual genes) or full chromosomal sequencing. If he only did genomic, he conveniently left out 99% of the DNA including important sequences like transcription regulatory regions.
Something else to ponder:
He managed to perfectly time the birth of these kids for paper submission and presentation at this huge conference, just 5 miles from his work. Science doesn’t work around conference schedules.
University of Wisconsin bioethicist Alta Charo said, “Having listened to Dr. He, I can only conclude that this was misguided, premature, unnecessary, and largely useless.”
