Stargardt disease, the most common form of juvenile macular degeneration, results from biallelic mutations in the ABCA4 gene. In a recently published study, researchers at the Institute of Molecular and Clinical Ophthalmology Basel and collaborators proposed a novel dual AAV vector system to deliver a split-intein adenine base editor for precise correction of the most common Stargardt mutation, c.5882G>A (p.Gly1961Glu).
