The prevalence of Pitt-Hopkins Syndrome is estimated to be around 1 in 25,000 to 30,000 individuals worldwide. However, due to underdiagnosis and misdiagnosis, the actual prevalence may be higher. PTHS affects both males and females across different ethnicities.
Individuals with Pitt-Hopkins Syndrome often experience severe intellectual disability, limited speech development, and motor delays. They may also exhibit distinctive facial features such as a wide mouth, deep-set eyes, and a prominent nasal bridge. Additionally, many individuals with PTHS have gastrointestinal issues, breathing difficulties, and seizures.
Early diagnosis and intervention are crucial in managing the symptoms and providing appropriate support for individuals with Pitt-Hopkins Syndrome. Genetic testing is typically required to confirm the diagnosis.
