A new base editor efficiently changes A to G DNA letters with fewer unintended edits

SpRY-ABE8e increases A-to-G editing efficiency while decreasing RNA off-target effects.

• Adenine base editors can create specific mutations, useful for correcting certain genetic variants.
• The new editor, SpRY-ABE8e, narrows the editing range and enhances efficiency for specific target sequences.
• SpRY-ABE8e shows improved precision for addressing G·C-to-T·A pathogenic variants compared to its predecessor.
• A new bioinformatics tool was created to support the development of precise adenine base editors.
