Abstract: Described herein are systems, methods, and compositions for the precise editing of DNA sequence(s) at specific loci to alter expression of target gene products at the pre-transcriptional or post-transcriptional level in a durable fashion, termed Stable and Heritable Alteration by Precision Editing (SHAPE). The SHAPE platform utilizes genetic modifiers (e.g., nucleases, (CRISPR guided) transposases, recombinases, base editors, and prime editors) to install specific sequence motifs at target sequences through precision genome engineering.
