Which of the following is NOT a feature of Prader-Willi Syndrome?

Prader-Willi Syndrome (PWS) is a genetic disorder characterized by a number of distinct features. Among these, hypotonia at birth is common, affecting muscle tone and leading to difficulties with motor skills. Individuals with Prader-Willi Syndrome typically exhibit obsessive eating behaviors due to an insatiable appetite, which is a central feature of the condition. Learning disabilities are also prevalent among affected individuals, as they tend to have intellectual impairments that vary widely across the spectrum.

Hyperactivity, however, is not characteristic of Prader-Willi Syndrome. In fact, individuals with PWS often experience low energy levels and may struggle with inactivity rather than displaying hyperactive behavior. Therefore, hyperactivity can be considered an atypical feature in this context, making it the correct choice for the question regarding what is NOT a feature of Prader-Willi Syndrome. Understanding these distinct traits helps differentiate PWS from other genetic and developmental disorders.
