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).
