A widely publicized study that suggested that the first gene-edited babies could have shorter life spans has been retracted due to crucial errors in the analysis.

The study, which was originally published June 3 in the journal Nature Medicine, showed that a genetic mutation that protects against HIV infection was linked with an increased risk of death before age 76, Live Science previously reported. This mutation, known as CCR5-delta 32, is the same genetic tweak that a Chinese scientist attempted to make in twin babies born last year in a highly controversial experiment using CRISPR technology.

Time - Study - Authors - Nature - Medicine

At the time the study was published, the authors of the Nature Medicine paper said that the work underscored concerns about the use of gene-editing technology in humans.

However, technical errors in the Nature Medicine paper caused the authors to undercount the number of people in their population with the CCR5-delta 32 mutation, Nature News...
