A high-fidelity Cas9 mutant delivered as a ribonucleoprotein complex enables efficient gene editing in human hematopoietic stem and progenitor cells
Open accessAbstract
Translation of the CRISPR–Cas9 system to human therapeutics holds high promise. However, specificity remains a concern especially when modifying stem cell populations. We show that existing rationally engineered Cas9 high-fidelity variants have reduced on-target activity when using the therapeutically relevant ribonucleoprotein (RNP) delivery method. Therefore, we devised an unbiased bacterial screen to isolate variants that retain activity in the RNP format. Introduction of a single point mutation, p.R691A, in Cas9 (high-fidelity (HiFi) Cas9) retained the high on-target activity of Cas9 while reducing off-target editing. HiFi Cas9 induces robust AAV6-mediated gene targeting at five therapeutically relevant loci (HBB, IL2RG, CCR5, HEXB, and TRAC) in human CD34+ hematopoietic stem and progenitor cells (HSPCs) as well as primary T cells. We also show that HiFi Cas9 mediates high-level correction of the sickle cell disease (SCD)-causing p.E6V mutation in HSPCs derived from patients with SCD. We anticipate that HiFi Cas9 will have wide utility for both basic science and therapeutic genome-editing applications. A bacterial screen yields a Cas9 variant that retains high on-target activity when delivered in the RNP format. As proof of principle, this Cas9 variant enables high-level correction of the sickle cell disease mutation in patient-derived HSPCs.

The paper’s Abstract reports RNA-guided Cas9 cleavage of complementary DNA, and its Conclusions propose the system’s potential for genome editing. It does not report editing in mammalian cells or state that this application had revolutionized the field; the reported cleavage experiments used DNA substrates in vitro. (LLM, conf=0.88)

The Abstract reports engineering prokaryotic CRISPR/Cas systems so that RNA-guided Cas9 cleaves genomic targets in human and mouse cells. It describes this as a new class of genome-engineering tools with wide applicability in mammalian cells; “revolutionized” is the citing authors’ characterization of that significance.

The Introduction identifies Cas9 as an RNA-guided nuclease derived from a microbial CRISPR system. “CRISPR-Cas9: From Yogurt to Genome Editing” reports that bacterial CRISPR systems were engineered to direct DNA cleavage and genome editing in mammalian cells, followed by rapid adoption. The paper thus supports the citing sentence’s broad characterization, though it does not use the word “revolutionized.” (LLM, conf=0.91)

The Discussion (page unavailable) describes RNP electroporation as a transient “hit-and-run” approach that enables efficient editing and reduces concerns about off-target cleavage.

The Discussion reports efficient editing in human HSPCs with minimal genic off-target activity and notes that RNP delivery has been associated with reduced off-target effects. But our copy does not establish an initial high level followed by rapid decay, or show that such a pulse causes fewer off-target effects.

“While cleavage at sites with perfect complementarity to the protospacer domain of the gRNA typically occurs with highest efficiency, cleavage at sites having one to several bases of mismatch with the gRNA can occur. These undesired cleavage events are called “off-target effects” (OTEs)10, and their existence should be minimized for therapeutic applications of genome editing technologies.”

The Results section ('HDR-mediated editing in HSPCs by ZFN mRNA and AAV6 donors'; page unavailable) identifies AAV6 as an effective vehicle for delivering homologous donor templates to CD34+ HSPCs.

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.
A language model drew the claims from the paper on 2026-09-27 (prompt extract-v2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
