Answer

Prader-Willi syndrome has been reported worldwide. Reported prevalence rates for Prader-Willi syndrome range from 1 per 8000 population in rural Sweden to 1 per 16,000 population in western Japan. [30, 31] Despite findings that suggest a prevalence rate of 1 per 52,000 population in the United Kingdom, Whittington et al estimate that the actual prevalence rate is higher and propose a true prevalence rate of 1 per 45,000 population.
