Prader-Willi syndrome is a disorder caused by loss of genetic material from proximal arm of chromosome 15. An important characteristic of Prader-Willi syndrome is a continuous sense of hunger that usually begins at around 2 years of age. Persons with Prader-Willi syndrome want to eat constantly because they never feel full (hyperphagia) and usually have trouble controlling their weight. Many problems of Prader-Willi syndrome are due to obesity. The common features of this disease are mental retardation, short stature, small hands and small feet etc.
