China fires two researchers after an investigation into a gene-editing trial in which a child died
Shanghai authorities on Friday released the findings of an investigation into a gene-editing study at Shanghai Jiao Tong University's School of Medicine, in which a six-year-old girl died a week after receiving an experimental treatment at Xinhua Hospital in March 2025. Two lead researchers, surnamed Qiu and Yang, were dismissed and barred for five years from science and technology programs. Investigators found the team broke research rules, did not share worrying monkey-test results with the child's doctors, and did not promptly disclose her death when publishing a paper in Nature.
Key points
- A six-year-old girl died on 31 March 2025, a week after an experimental gene-editing treatment at Shanghai's Xinhua Hospital; the hospital's ethics committee tied her death to a gene-therapy complication.
- The official investigation found rule-breaking, monkey-test warnings not shared with her doctors, and her death not promptly disclosed in a Nature paper.
- Lead researchers Qiu and Yang were dismissed and barred for five years from science and technology programs and honours.
What happened
The study was an investigator-initiated trial, a category of early-stage clinical study that has grown quickly in China in recent years, particularly in cell and gene therapies. The case drew wide attention after Science reported the child's death in July.
The treatment was described by the researchers as the world's first attempt to edit genes inside a human brain, aimed at the child's rare genetic disorder, for which no effective treatment exists.
What we know / what we don't know yet
What we know
- The investigation's findings: rule-breaking by the research team, undisclosed monkey-test warnings, and the child's death not promptly disclosed in the Nature paper.
- That researchers Qiu and Yang were dismissed and barred for five years, and others disciplined.
What we don't know yet
- Whether any of the researchers face criminal charges or further legal consequences — the findings announced no such step.
- The family's position — no public statement from the child's family was reported with the findings.

Why this label: The timeline, the diagnosis and the ethics committee's determination are from the official investigation's findings, released on Friday and reported by CCTV News and People's Daily, and carried in the same terms by the South China Morning Post and Bloomberg.
On the ladder: a claim earns Verified from primary evidence, or from two independent sources that do not copy each other.
Why this label: The findings are the investigation's own conclusions, reported by People's Daily from CCTV News and in matching terms by Bloomberg and the South China Morning Post; they are official findings about the team's conduct, not a court's verdict.
On the ladder: a claim earns Verified from primary evidence, or from two independent sources that do not copy each other.
Why this label: The dismissals and the five-year bar are the investigation's announced sanctions, reported by People's Daily and Bloomberg from CCTV's report of the findings.

Why it matters
A child died in a first-of-its-kind brain gene-editing trial, and the official account now says the warnings were there before the treatment went ahead — in monkey tests her doctors never saw — and that her death stayed out of the paper that followed. The findings are China's fullest official reckoning yet with how experimental gene-therapy trials are overseen.
