Loss-of-function mutations inPNPLA1, a gene encoding an enzyme with unknown function, cause dry and scaling skin in humans. Using mouse models with PNPLA1 deficiency, the authors show that PNPLA1 participates in the biosynthesis of acylceramide, a lipid component essential for skin barrier function.
