abstract = {The performance of CRISPR-mediated genome editing near
inverted repeats (IRs) potentially results in chromosomal
translocations and other catastrophic rearrangements.
However, the extent of this risk may be significantly
underestimated because current reporter systems focus solely
on site-specific translocations. Here, trans-acting reporter
systems in Escherichia coli are developed to detect
nontargeted translocations. Markedly increased frequency of
translocations following CRISPR-Cas9 activation is observed,
with the magnitude determined primarily by the length of the
IRs and the proximity between Cas9 target sites and IRs.
These translocations arise through a combination of
intramolecular single-strand annealing and alternative
end-joining mechanisms. Furthermore, it is discovered that
introducing segments homologous to IR loci can substantially
mitigate nontargeted translocations without significantly
compromising CRISPR-Cas9-mediated editing. The study
provides valuable insights into the genetic risks associated
with CRISPR technologies and suggests a viable strategy for
developing genetically safer CRISPR systems.},
