Article Excerpts about Prader-Willi syndrome

Prader-Willi syndrome (PWS) is an uncommon inherited disorder characterized by mental retardation, decreased muscle tone, short stature, emotional lability and an insatiable appetite which can lead to life-threatening obesity. The syndrome was first described in 1956 by Drs. Prader, Labhart, and Willi. (Source: Genes and Disease by the National Center for Biotechnology)

Definitions of Prader-Willi syndrome:

A syndrome characterized at birth by the lack of spontaneous movements and protective reflexes, thus giving an appearance of severe brain damage. Profound hypotonia may cause asphyxia. Sucking and swallowing reflexes are absent or decreased. Deficient thermoregulation, amyotonia, and hypogonadism are usually associated. After a few weeks or months, the affected infants become more responsive and more alert. Areflexia disappears gradually but hypotonia may persist longer. This phase is marked mainly by mental subnormality, delayed growth and motor development, speech defect, lack of emotional control, voracious appetite leading to obesity, hypotonia, hyperlaxity, delayed bone maturation, and multiple orofacial and other disoders. There is a tendency to develop diabetes mellitus and cardiac failure in some patients. Pain insensitivity is common. Prader-Willi habitus associated with osteopenia and camptodactyly is known as the Urban-Rogers-Meyer syndrome. - (Source - Diseases Database)

Prader-Willi syndrome is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Prader-Willi syndrome, or a subtype of Prader-Willi syndrome, affects less than 200,000 people in the US population.

Ophanet, a consortium of European partners, currently defines a condition rare when it affects 1 person per 2,000. They list Prader-Willi syndrome as a "rare disease".
