Unreported death in Chinese gene‑editing trial revealed

scienceJul 23, 202619338

Science and Retraction Watch reveal that a six-year-old girl died after an experimental base-editor infusion in China that was never publicly disclosed. Parents paid roughly $860,000 for the n-of-1 treatment; seven days after clinicians infused trillions of virus particles carrying the base editor into her spinal fluid, she died of a severe immune reaction linked to the therapy. The investigation reports that researchers published proof-of-concept animal work showing success in mice while omitting the familys role and its financial contributions, and that serious side effects had been observed in primate studies that were not shared with the family. The family is now seeking accountability, and scientists quoted in the reporting called aspects of the trial avoidable. The story raises specific questions about transparency in clinical translation, undisclosed conflicts in publications, and whether journals should revisit the related papers.
