The invention discloses a DNA methyltransferase inhibitor, or a pharmaceutically acceptable salt thereof, for use in treating Rett syndrome. Further disclosed is a pharmaceutical composition comprising a DNA methyltransferase inhibitor, or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier for use in treating Rett syndrome. Further disclosed is an in vitro method for diagnosing Rett syndrome in a subject comprising the step of analysing DNA methylation in a sample of the subject. Further disclosed is a kit for diagnosing Rett syndrome in a subject in vitro comprising reagents for quantifying a level of DNA methylation in a sample of the subject, wherein an increased level of DNA methylation in the sample compared to a reference value obtained from a reference sample of a healthy individual indicates that the subject has Rett syndrome.
