Prader-Willi Syndrome (PWS) is a group of symptoms caused by a genetic defect in Chromosome 15. PWS occurs in about one of every 15,000 births. Symptoms of Prader-Willi Syndrome can include impaired body control, mental retardation, hypotonia during infancy, short stature, insatiable appetite beginning after infancy, scratching and skin picking, and behavior difficulties.
