Abstract

In this issue, Apaydin and Sadhnani et al. report in situ genome editing of human skin to correct a common disease-causing mutation underlying autosomal recessive congenital ichthyosis (ARCI).<sup>1</sup> They combine a base editor, transient barrier modulation, and topical mRNA-lipid nanoparticle administration to restore clinically meaningful levels of transglutaminase 1 activity.
