Concerns over a Chinese scientist's claim that he created the first gene-edited babies grow with more questions about whether it worked and the possible harm he may have inflicted on the twin girls.

The Second International Summit on Human Genome Editing issues a consensus on how scientists might responsibly move forward to create gene-edited babies in the wake of a rogue scientist's claims.

He Jiankui, who shocked the world by asserting he had genetically edited twin girls, faced growing criticism from other researchers as he spoke at a scientific conference in Hong Kong.

A scientist says he created the first genetically edited babies using CRISPR to protect them from HIV infection. The move has prompted immediate criticism as premature and reckless.

More than a third of patients with cancer of the esophagus responded to experimental treatment in China with the gene-editing technique CRISPR. Several CRISPR studies are underway there.

Success with a new gene-editing technique in mice prone to deafness highlights the potential for using it to prevent a form of inherited hearing loss in humans. But it has many hurdles to overcome.
