Answer 1

Angelman syndrome is caused by a genetic mutation on chromosome 15.

Step-by-step explanation:

Angelman syndrome is caused by a genetic mutation on chromosome 15. The name of this gene is UBE3A. Normally, people inherit one copy of the gene from each parent, and both copies become active in many areas in the body. Angelman syndrome occurs when only one copy of the gene is active in certain areas of the brain.
