Adenine base editing correction of LMNA c.745C>T (p.R249W) in congenital muscular dystrophy myoblasts improves cellular phenotype while revealing deleterious p.L248P bystander effects
These results demonstrate that ABE can effectively target the LMNA c.745C>T mutation but also reveal the significant impact of bystander edits on cellular physiology, underscoring the necessity of precise editing technologies to ensure both efficacy and safety in future clinical translation.
