Final answer:
The incidence of PWS is 1 in 10,000 to 1 in 15,000 live births. PWS is a genetic disorder characterized by physical, cognitive, and behavioral abnormalities. PWS is associated with symptoms such as weak muscle tone, developmental delays, distinct facial features, excessive appetite, and obesity.
Step-by-step explanation:
The incidence of PWS is 1 in 10,000 to 1 in 15,000 live births.
Prader-Willi Syndrome (PWS) is a genetic disorder characterized by various physical, cognitive, and behavioral abnormalities. PWS is caused by the deletion or inactivation of certain genes on chromosome 15.
While the majority of recognized etiologies of birth complications are genetic, environmental factors can also play a role in some cases.
PWS is associated with a range of symptoms including hypotonia (weak muscle tone), developmental delays, distinct facial features, hyperphagia (excessive appetite), and obesity.
