Mutations in the rhodopsin () gene are the predominant causes of autosomal dominant retinitis pigmentosa (adRP). Given the diverse gain-of-function mutations, therapeutic strategies targeting specific sequences face significant challenges. Here, we provide a universal approach to conquer this problem: we have devised a CRISPR-Cas12i-based, mutation-independent gene knockout and replacement compound therapy carried by a dual AAV2/8 system. In this study, we successfully delayed the progression of retinal degeneration in the classic mouse disease model , and also , a new native mouse mutation model we developed. Our research expands the horizon of potential options for future treatments of RHO-mediated adRP.
