Mutations in MECP2 cause Rett syndrome. The authors show that a MeCP2-HDAC3 complex positively regulates a subset of neuronal genes through FOXO recruitment and deacetylation, and that HDAC3 loss contributes to cognitive and social deficits in mice. Rett-patient-derived cells exhibited similar HDAC3-FOXO-mediated transcriptional impairments and were rescued by gene editing.
