Abstract: Genomic insertions, duplications, and insertion/deletion (indels) account for ˜14% of human pathogenic mutations. Current gene editing methods cannot accurately or efficiently correct these abnormal genomic rearrangements, especially larger alterations (>100 bp). The presently disclosed compositions and methods accurately delete insertions/duplications and repair the deletion junction to improve the scope of gene therapies. For example, a Cas9 prime editor (PECas9) is combined with two prime editing guide RNAs (pegRNAs) targeting complementary DNA strands. PECas9 can replace an ˜1-kb genomic fragment with a desired sequence at the target site without requiring an exogenous DNA template.
