Columbia study: embryo base editing reaches all cells but brings unpredictable changes
A Columbia University study reports that new gene-editing techniques can accurately edit genes in human embryos, but the work also uncovered risks that currently rule out clinical use.

Researchers at Columbia University Vagelos College of Physicians and Surgeons report that new gene-editing techniques can accurately edit genes in human embryos. The work describes base editing that can reach all cells, but it also causes unpredictable genetic changes.
The report says the techniques give scientists indispensable tools for understanding normal human development. It also uncovered important risks that currently preclude use of the techniques in the clinic.
How often the unpredictable changes occur, and what they mean for safety, remains an open question.
Our view
This is a research-tool result rather than a clinical breakthrough: the techniques can reach all cells but produce unpredictable genetic changes, and the risks keep them out of the clinic for now.
What the reporting says: The reporting says a Columbia University study found new cutting-edge techniques can accurately edit genes in human embryos, giving scientists indispensable tools for understanding normal human development, while also uncovering important risks that currently preclude clinical use.
