Here we show that CRISPR-Cas9 editing can introduce unintended mutations in vivo, which are passed on to the next generation. By editing fertilized zebrafish eggs using four guide RNAs selected for off-target activity in vitro, followed by long-read sequencing of DNA from >1100 larvae, juvenile and adult fish across two generations, we find that structural variants (SVs), i.e., insertions and deletions \u226550 bp, represent 6% of editing outcomes in founder larvae. These SVs occur both at on-target and off-target sites. Our results also illustrate that adult founder zebrafish are mosaic in their germ cells, and that 26% of their offspring carries an off-target mutation and 9% an SV. Hence, pre-testing for off-target activity and SVs using patient material is advisable in clinical applications, to reduce the risk of unanticipated effects with potentially large implications.", "doi": "10.1038/s41467-022-28244-5", "pmid": "35110541", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC8810904"}, {"db": "pii", "key": "10.1038/s41467-022-28244-5"}], "notes": [], "created": "2026-09-23T06:46:03.836Z", "modified": "2026-09-23T06:46:03.932Z"}
