The Precision Problem: How Off-Target CRISPR Edits Threaten the Future of Gene Editing Therapies
CRISPR-based therapies are entering human trials at an accelerating pace, but a persistent technical vulnerability — unintended edits at genomic sites other than the intended target — continues to raise serious questions about patient safety and long-term efficacy. Detection methods are improving, but the field has yet to establish consensus on what constitutes an acceptable level of off-target activity, and regulators are watching closely.
