The cause

The mutation is that some genes are missing. chromosome 15 is the one that is missing genes and it has PWS. The gene that is missing is called OCA2.


Currently there are no cures for PWS. You can go to therapy when you have PWS but you will still have it. If you don't go to therapy then you might have chances of getting other things.
