Angelman Syndrome: A Rare Genetic Disorder

What is Angelman Syndrome?

Angelman syndrome is a rare genetic disorder that affects the nervous system. It is characterized by intellectual disability, speech impairment, motor difficulties and specific behavioral characteristics. The cause of Angelman syndrome is a problem with the UBE3A gene, which is located on the 15th chromosome. In typical humans, the UBE3A gene is expressed from the maternal chromosome. However, in people with Angelman syndrome, the UBE3A gene is either missing or not expressed from the maternal chromosome. This lack of UBE3A gene expression leads to the symptoms of Angelman syndrome.
