Highly Parallel Profiling of Cas9 Variant Specificity

Open access

Abstract

Determining the off-target cleavage profile of programmable nucleases is an important consideration for any genome editing experiment, and a number of Cas9 variants have been reported that improve specificity. We describe here tagmentation-based tag integration site sequencing (TTISS), an efficient, scalable method for analyzing double-strand breaks (DSBs) that we apply in parallel to eight Cas9 variants across 59 targets. Additionally, we generated thousands of other Cas9 variants and screened for variants with enhanced specificity and activity, identifying LZ3 Cas9, a high specificity variant with a unique +1 insertion profile. This comprehensive comparison reveals a general trade-off between Cas9 activity and specificity and provides information about the frequency of generation of +1 insertions, which has implications for correcting frameshift mutations.

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.
