Multiple Exon Skipping in the Duchenne Muscular Dystrophy Hot Spots: Prospects and Challenges

Multiple exon skipping is a promising therapy for Duchenne Muscular Dystrophy (DMD), targeting genetic hot spots like exons 45–55 and 3–9 to restore dystrophin. While PMOs have shown potential, challenges in delivery remain. Advances like vivo-PMOs aim to enhance uptake. Despite promising preclinical results, clinical validation is needed to ensure effectiveness and long-term safety. Ongoing research focuses on optimizing delivery and broadening patient eligibility for exon-skipping therapies.
