About Dup15q

Chromosome 15q11.2-13.1 duplication syndrome  is a clinically identifiable syndrome which results from duplications of chromosome 15q11.2 -13.1.

These duplications most commonly occur in one of two forms. These include an extra isodicentric 15 chromosome, abbreviated idic(15), or an interstitial duplication 15, abbreviated int dup(15). When the duplicated material comes from the maternal chromosome, developmental problems are often the result. In most cases of chromosome 15q duplication syndrome, the chromosome duplication is not inherited, but occurred as a random event during the formation of reproductive cells.
