Genomic insertions, duplications and insertion/deletions (indels), which account for ~14% of human pathogenic mutations, cannot be accurately or efficiently corrected by current gene editing methods, especially those that involve larger alterations (>100 bp). Here, we optimize prime editing tools for creating precise genomic deletions and direct the replacement of a genomic fragment ranging from ~1-kb to ~10-kb with a desired sequence in the absence of an exogenous DNA template. By conjugating Cas9 nuclease to reverse transcriptase (PE-Cas9) and combining it with two prime editing guide RNAs (pegRNAs) targeting complementary DNA strands, we achieve precise and specific deletion and repair (PEDAR) of target sequences. PEDAR outperformed other genome editing methods in a reporter system and at endogenous loci, efficiently creating large and precise genomic alterations. In a mouse model of tyrosinemia, PEDAR removed a 1.38-kb pathogenic insertion within the Fah gene and precisely repaired the deletion junction to restore FAH expression in liver. Prime editing is expanded to deletions and replacements of genomic sequences of up to 10kb.
