2. Symptoms of Prader-Willi Syndrome
Infancy and Early Childhood
Childhood to Adulthood
3. Causes and Risk Factors
PWS is caused by genetic changes on chromosome 15, specifically in the “Prader-Willi critical region” (PWCR). These changes can occur in three ways:
PWS typically occurs randomly during conception and is not inherited. There are no specific risk factors, but genetic counseling is recommended for families with a history of PWS.
4. Diagnosis and Testing
Early diagnosis is crucial for implementing appropriate support strategies. PWS is diagnosed through:
Genetic testing can diagnose nearly all cases of PWS in infants.
5. Treatment and Management
While there’s no cure for PWS, treatment focuses on managing symptoms.
6. Long-term Outlook
The median age of death for people with PWS is 30 years, but life expectancy can range from 1 month to 58 years. With advances in care, the mortality rate has decreased by about 1.25% per year.Adults with PWS may require:
