Methyl-CpG-binding protein 2
The MECP2 gene encodes a protein that is involved in epigenetic regulation. In particular it plays a role in methylation of CpG islets. Mutations lead to several -linked disorders such as dominant Rett syndrome and recessive mental retardation. Also participation in autism and hypomethylation syndrome is discussed.
