Sérgio Sousa and colleagues show that Lenz-Majewski syndrome, a disorder featuring generalized craniotubular hyperostosis, results from de novo gain-of-function mutations in PTDSS1. The mutations lead to increased phophatidylserine synthesis, suggesting a link between phosphatidylserine production and bone metabolism.
