Abstract

Highly specific Cas9 nucleases derived from SpCas9 are valuable tools for genome editing, but their wide applications are hampered by a lack of knowledge governing guide RNA (gRNA) activity. Here, we perform a genome-scale screen to measure gRNA activity for two highly specific SpCas9 variants (eSpCas9(1.1) and SpCas9-HF1) and wild-type SpCas9 (WT-SpCas9) in human cells, and obtain indel rates of over 50,000 gRNAs for each nuclease, covering ~20,000 genes. We evaluate the contribution of 1,031 features to gRNA activity and develope models for activity prediction. Our data reveals that a combination of RNN with important biological features outperforms other models for activity prediction. We further demonstrate that our model outperforms other popular gRNA design tools. Finally, we develop an online design tool DeepHF for the three Cas9 nucleases. The database, as well as the designer tool, is freely accessible via a web server, http://www.DeepHF.com/ .

  • Most gRNA prediction tools rely on either traditional algorithms or deep learning and focus only on SpCas9-WT; few models are specific to variants.

    “Although some gRNA prediction tools have been developed, most of them rely on either traditional algorithms (Rule Set 1, CRISPRscan, etc.) or deep learning (DeepCRISPR, DeepCas9, etc.) and focus only on SpCas9-WT; few models are specific to variants (DeepSpCas9variants, DeepSmallCas9, GuideVar, DeepSniper, etc.).”
  • The pattern of SpCas9-NG is similar to SpCas9-WT.

    “The pattern of SpCas9-NG is similar to SpCas9-WT.”

    The Introduction and Results passages compare WT-SpCas9 with eSpCas9(1.1) and SpCas9-HF1, not SpCas9-NG. Searches for “SpCas9-NG” and its similarity to WT-SpCas9 found no passage addressing that comparison; page numbers were unavailable in our copy. (LLM, conf=0.76)

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.
