Abstract

The clustered regularly interspaced short palindromic repeats (CRISPR)-Caspase9 (Cas9) system provides a programmable technology that may be used to edit the eukaryotic genome and epigenome. CRISPR/Cas9 includes a guide RNA targeted to a gene of interest which hybridizes to a nucleotide sequence next to a protospacer-adjacent motif (PAM) which guides the Cas9 endonucleases to the target site for cleavage via double-strand breaks. A caveat of the CRISPR/Cas9 system is the creation of off-target double-strand breaks (DSBs) which may result in anomalous insertions, deletions, and translocations. Thus, assays for the sensitive detection and analysis of off-target editing are critical. Here, we describe currently available CRISPR technologies, CRISPR applications, and current analysis platforms to detect off-target effects including genome-wide, unbiased identification of DSBs enabled by sequencing (GUIDE-Seq), high-throughput genomic translocation sequencing (HTGTS), breaks labeling, enrichments on streptavidin and next-generation sequencing (BLESS), and in vitro nuclease-digested genome sequencing (Digenome-seq).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
