Scientists have developed a new gene-editing system that can weave whole genes into human DNA. It could one day lead to a better method of treating genetic diseases triggered by a diverse range of mutations.
So far, the approach has been tested only in human cells in the laboratory. But if it's shown to be safe and effective for patients, it could provide an alternative to gene-editing tools that target only specific typos in DNA. Rather than correcting a single gene mutation, the new technique would instead introduce a working copy of the gene into a person's cells.
