Yes, Angelman Syndrome (AS) is classified as an autism spectrum disorder (ASD). AS is a rare genetic disorder that is caused by a mutation in the UBE3A gene, which is located on chromosome 15. This mutation results in a number of physical, developmental, and neurological impairments, including intellectual disability, developmental delay, and difficulty communicating and interacting with others.
These impairments are hallmarks of an ASD diagnosis, which also includes difficulties with social interaction, communication, and repetitive behaviors. Additionally, those with AS often exhibit behaviors that are similar to those seen in other ASD diagnoses, such as hand flapping, clapping, and rocking.
There are also other characteristics associated with AS that are similar to those seen in ASD, such as sleep disturbances, hyperactivity, and a tendency to be easily distracted. Furthermore, research has shown that those with AS are more likely to have a co-occurring ASD diagnosis than those without AS.
Because of the similar impairments and behaviors associated with AS and other ASD diagnoses, AS is classified as an autism spectrum disorder. While there is still much to learn about AS, it is clear that it is closely linked to ASD and should be treated as such.
