NEW CASENEW EVIDENCE
CRISPR off-target evidence
Edited cells show 82% desired gene correction. Sequencing finds an unintended edit in 6% of cells at site Z; controls show 0.2%. Cell survival is unchanged over seven days.
Efficacy and off-target risk both matter.
Short survival follow-up does not establish long-term safety.
