CRISPR Gene Editing Can Cause Hundreds of Unintended Mutations

Webb6 feb. 2024 · Unforeseen off-target edits can be generated when the CRISPR/Cas systems do not cleave only the target region, and may cause potentially harmful effects, for example by activation of oncogenes. 57, 58 As mentioned above, off-target mutations may cause genome instability and disrupt gene function. 43 The sgRNA-dependent and … WebbThe use of a Cas9 nickase will minimize off-target damage. The Cas9 nickases only cut one strand but can still target a genome edit. However, an off-target nick, relative to a double-stranded break, is easier to accurately repair. There are also modified Cas9 proteins that offer higher specificity than wild type. The terminology is confusing.
