Prime Editing Exhibits Limited Genome-Wide Off-Target Effects in Cellular and Embryonic Gene Editing.

Abstract excerpt

Prime editing (PE) is a precise genome-editing technology that avoids double-strand breaks, holding great promise for clinical and agricultural applications. However, its genome-wide off-target effects are not fully understood, raising safety concerns. Here, we systematically compared the safety profiles of four prime editor variants (PE2max, PE3max, PE4max, and PE5max) using PEM-seq and RNA-seq. We further...
