Because it was first described by a British paediatrician called Doctor Harry Angelman, in 1965. It was previously sometimes known as "happy puppet syndrome" due to sufferers' jerky movements and generally happy appearance but this name is now considered pejorative.
Also because of there happy youthful expression.

Angelman syndrome's scientific name is "AS," or "Angelman syndrome." It is a genetic disorder characterized by developmental delays, speech impairments, and unique behaviors. It is caused by a loss of function in a specific gene located on chromosome 15.
Angelman syndrome is a genetic disorder, as is Down syndrome. But they are not the same. Angelman Syndrome involves a deletion of Chromosome 15, whereas people with Down syndrome have an extra copy of Chromosome 21.
Approximately 1 in 15,000 - 20,000 babies is born with Angelman syndrome, making it a rare genetic disorder.
Yes. All races and both males and females get Angelman Syndrome.
People with Angelman Syndrome often live the average life expectancy of their gender.
It is recessive
no
"Autosomal" means the syndrome or disorder of interest is pertaining to a chromosome that is not a sex chromosome, either X or Y. Angelman and Prader-Willi Syndrome are both caused by a deletion (or disruption of a gene) on chromosome 15, which is an autosomal chromosome and not a sex chromosome. Therefore, yes, Angelman syndrome is considered an autosomal syndrome.
Mice and humans are used in researching Angelman Syndrome. In mice, the condition is genetically induced, and then a medical trial treatment is applied. In humans, previously approved treatments for other illnesses are used on individuals that were born with Angelman Syndrome.
molecular genetic testing?
People with Angelman Syndrome usually have a normal life span unless they have it severe or a bad rare kind of it. This can be followed up by looking for the symptoms.
