 Recently, the study of epigenetic regulation has been expanded to the neuronal developmental disorder from carcinogenesis, embryogenesis and tissue differentiation. For example, from Rett syndrome with autism and epilepsy is associated with aberrant epigenetic control with mutation of MeCP2. Target genes of MeCP2 show abnormal expressions in the brain. Unlike alternation of DNA sequence mutation, the epigenetic control including DNA methylation is reversible, and the epigenetic programming can be corrected with life. Therefore, the DNA methylation is affected by environment and nutrition factor.
