An important gene associated with Gene Duplication Disease is MECP2 (Methyl-CpG Binding Protein 2), and among its related pathways/superpathways are Neuroscience and Transcriptional Regulation by MECP2. Affiliated tissues include heart, and related phenotypes are nervous system and homeostasis/metabolism
