- compulsive behavior.
Many of those affected also have sleep problems. Other symptoms can include

Causes of Prader-Willi syndrome
The loss of genes in a specific region of chromosome 15 from the paternal copy (the gene that was inherited from the father) causes Prader-Willi syndrome. However, most cases of Prader-Willi syndrome are not inherited. Instead, the genetic changes occur as random events during the formation of reproductive cells (eggs and sperm) or in early embryonic development.
