Prime Editing Corrects the HBB Codon 8/9 (+G) Mutation in Patient-Derived Induced Pluripotent Stem Cells and Restores β-Globin Expression in iPSC-Derived Erythroid Cells
Background Homozygosity for the HBB codon 8/9 (+G) frameshift (c.27dup (p.Ser10ValfsTer14)) causes transfusion-dependent β⁰-thalassaemia and is common in South Asia. Prime editing can reverse this insertion without double-strand breaks or donor DNA, but its efficiency depends on pegRNA design. Methods We derived Sendai...
