Following Cas9 cleavage, DNA repair without a donor template is generally considered stochastic, heterogeneous, and impractical beyond gene disruption. Here, we show that template-free Cas9 editing is predictable and capable of precise repair to a predicted genotype, enabling correction of human disease-associated mutations. We constructed a library of 2,000 Cas9 guide RNAs (gRNAs) paired with DNA target sites and trained inDelphi, a machine learning model that predicts genotypes and frequencies of 1- to 60-bp deletions and 1-bp insertions with high accuracy (r = 0.87) in five human and mouse cell lines. inDelphi predicts that 5–11% of Cas9 gRNAs targeting the human genome are “precise-50”, yielding a single genotype comprising ≥50% of all major editing products. We experimentally confirmed precise-50 insertions and deletions in 195 human disease-relevant alleles, including correction in primary patient-derived fibroblasts of pathogenic alleles to wild-type genotype for Hermansky-Pudlak syndrome and Menkes disease. This study establishes an approach for precise, template-free genome editing.
