Posted on: 26 July 2026, source: South China Morning Post A leading Chinese scientist is under investigation by his university after a six-year-old girl reportedly died following experimental gene-editing therapy. The girl, named Mei, died days after receiving a treatment designed to correct a genetic mutation affecting her neurodevelopment in March last year, according to a report published by Science following a joint investigation with Retraction Watch, a non-profit organisation that monitors retracted research. Her parents said she had suffered a fatal immune reaction linked to the treatment. {fastsocialshare}
