What Is Prader Willi Syndrome?
2. Causes
As mentioned, Prader-Willi syndrome is a type of genetic disorder. The exact cause of the disorder is not well understood, but we do know that genes in chromosome 15 are affected. In Prader-Willi syndrome it is certain paternal genes that are responsible for the condition, which means those that are passed on from the father.
However, the disorder is usually down to a random genetic copying error, which means it is not necessary for the father to have the faulty in their genes. The disorder will cause problems with the functioning of the hypothalamus. This is a part of the brain that is responsible for processes like development, sleep, mood, growth, and hunger.
