Prader-Willi syndrome (PWS) is not classified as a recessive or sex-linked condition; instead, it is primarily caused by the loss of function of genes on the paternal chromosome 15 due to deletion, uniparental disomy, or imprinting defects. The genetic mechanisms involved are complex and typically arise from errors during the formation of sperm or egg cells. Therefore, PWS is considered a genetic disorder with specific chromosomal abnormalities rather than a simple Mendelian inheritance pattern.
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.
Yes he does.
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.

1 in 15,000 people have it
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.
Chromosome 15q partial deletion is the name for this syndrome.
Prader-Willi Syndrome.
It was named after the two doctors who diagnosed it
