Chromosomal Duplication Syndrome is related to chromosome xp11.23-p11.22 duplication syndrome and chromosome 22q11.2 duplication syndrome. An important gene associated with Chromosomal Duplication Syndrome is CBS (Cystathionine Beta-Synthase), and among its related pathways/superpathways are Alzheimer's disease and miRNA effects and Regulation of Insulin-like Growth Factor (IGF) transport and uptake by Insulin-like Growth Factor Binding Proteins (IGFBPs). Related phenotypes are Reduced mammosphere formation and growth/size/body region
