  • Abstract
  • Look Inside

 Rett syndrome is an X-linked dominant disease with several features such as autism and epilepsy. The causative gene of this syndrome, MeCP2, was found on the X chromosome in 1999. MeCP2 does not encode a neurotransmitter that has been expected, but encodes a key protein in a gene-suppression system, an epigenetic mechanism, via DNA methylation. This finding suggests that its pathogenesis would be over-expression of down stream gene(s)which are supposed to be controlled by MeCP2 in the brain. Failure of the epigenetic mechanism may cause not only Rett syndrome, but also cause other autism diseases and general mental diseases. To address this hypothesis and to find new therapeutic ways, I hope that a number of young psychiatrists will immerse in“neuroepigenomics”.
