Does Angelman syndrome come from mother or father?

Does Angelman syndrome come from mother or father?

Angelman syndrome is caused by a genetic mutation on chromosome 15. The name of this gene is UBE3A.

Angelman syndrome occurs when only one copy of the gene is active in certain areas of the brain.
