Prader-willi syndrome occurs due to genetic mutation, it is believed that parents with a genetic abnormality, uneffected by the syndrome, pass the mutation to their children. Some studies suggest that the syndrome is due to missing genes in the paternal chromosome, but it may be a combination of both parents.
1 in 15,000 people have it

Andrea Prader, Heinrich Willi, Alexis Labhart, Andrew Ziegler and Guido Franconi were first to observe Prader Willi Syndrome in 1956.
A person inherits Prader-Willi syndrome from the paternal chromosomes. This basically means that you had seven genes that were unexpressed.
Around 1 in 10,000 to 30,000 people are born with Prader-Willi Syndrome (PWS) each year. It is a rare genetic disorder caused by the loss of function of certain genes in chromosome 15.
Yes he does.
According to the research I've done, Prader-Willi Syndrome is rarely a result of translocation, but it is a possibility. Translocation in this syndrome results in an inactivation of genes on the paternal chromosome 15.
There are no guidelines for preventing Prader-Willi syndrome. Prader-Willi Syndrome is a result of a genetic "error" that occurs at conception therefore there is nothing that can be done to prevent it. Liken it to not being able to prevent hair color or eye color....two things that occur as a result of DNA at conception.
