Methyl-CpG-Bindungsprotein 2

Das MECP2-Gen kodiert ein Protein, welches in die epigentische Regulation insbesondere über die Methylierung der CpG-Inseln eingebunden ist. Mutationen führen zu x-chromosomal dominantem Rett-Syndrom oder zu rezessiver mentaler Retardierung. Weiterhin wird ein Zusammenhang mit Autismus und dem Hypomethylierungs-Syndrom diskutiert.
