Prader-Willi Syndrome (PWS) is a complex, sporadic condition occurring in all ethnic groups, affecting both males and females. Estimates of incidence vary between 1 in 10 000 to 1 in 15 000. The primary features of this genetic condition include infantile hypotonia (low muscle tone or floppiness), failure to thrive, hypogonadism and developmental delay. This is followed by the development of obesity (if food intake is not strictly controlled), short stature and intellectual and behavioural disabilities.
A parent support group, the Prader-Willi Syndrome Association of South Africa (PWSA SA) was formed in 1990, and now consists of more than 20 PWS families. The Association is in close contact with PWS support groups in other countries, particularly in the USA, UK and Scandinavia, and is a member of the International Prader-Willi Syndrome Organization (IPWSO).
