vPE: Developing a new type of highly accurate gene editing

The vPE prime editor is presented as a more precise genome-editing approach intended to improve stable edits and reduce indel errors.

This short review or commentary summarizes a recently reported engineered prime editor with nick-relaxing mutations that destabilize the unedited 5' strand.

The abstract reports promise for therapeutics and crop improvement but provides no new experimental results, quantitative performance data, or clinical evidence.
