Angelman Syndrome (AS) is a rare genetic disorder characterized by severe developmental delays, intellectual disability, ataxia, speech impediments, and other neurological issues. It is caused by a defect in the gene responsible for the production of the UBE3A protein.
Common physical characteristics of AS include a large head, an open mouth, and protruding tongue. Other physical features can include wide-set eyes, flat back of head, jerky arm and leg movements, and a short, wide stature.
The mental and intellectual development of individuals with AS is severely affected. Most individuals with AS have severe intellectual disability, and are unable to speak. They may have difficulty understanding language, and may have difficulty communicating in any way.
Behavioral issues are also common in those with AS, including hyperactivity, excitability, and impulsivity. These behaviors can affect the individual's quality of life, and can be difficult to manage.
Angelman Syndrome can be diagnosed with a genetic test or laboratory analysis. Treatment options for AS are limited, but can include physical therapy, speech therapy, occupational therapy, and behavioral therapy. Although there is no cure for AS, treatment can help to improve an individual's quality of life.
