摘要

Currently, there is no permanent treatment for the group of severe monogenic fragile skin conditions epidermolysis bullosa (EB). The recent US Food and Drug Administration (FDA)-approved in vivo gene replacement therapy beremagene geperpavec (Vyjuvek®) provides a promising solution, but it requires ongoing application and is not applicable to all forms of EB. Targeted gene editing approaches directly addressing pathogenic mutations hold great promise for the development of durable personalized therapies. Here, we comprehensively describe the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein (Cas) gene editing landscape for EB, critically review the advantages and limitations of emerging therapeutic strategies, and present some future perspectives. We find that the widespread application of Cas9 nuclease is currently hindered by off-target genotoxicity, which can be mitigated using Cas9 nickases. Further, new tools including prime editing have recently emerged and hold significant potential for EB gene therapy. Ongoing developments in gene editing technologies focused on improving safety and editing precision offer significant promise for the future clinical translation of potentially lifelong treatments for people with EB.
