Prader-Willi Syndrome is neither dominant or recessive - it is simply a genetic anomaly that occurs at conception (it's not inherited - it just happens) where part of the 15th chromosome that should be present/active is missing. This occurs either because it is totally missing (known as deletion) or because the child gets 2 chromosome 15s from the mother (instead of 1 from mom and 1 from dad which is the way it should be) and therefore that part of chromosome 15 that should be active from the father is nonexistent (this is known as uniparental disomy, or UPD)
Andrea Prader, Heinrich Willi, Alexis Labhart, Andrew Ziegler and Guido Franconi were first to observe Prader Willi Syndrome in 1956.
Life with Prader-Willi can be a difficult ride. Individuals with prader willi have a hard time ever feeling full. One of the scariest things is that someone with prader willi can actually eat themselves to death if they do not control themselves. Individuals with prader-willi have been known to self mutilate (not all individuals, but some do). If someone with prader-willi chokes it is possible that they can throw up their insides. A lot of individuals with prader- willi are slightly mentally retarded, but not all. People with prader willi have weak muscle mass, short stature and have distinct facial features. A lot of individuals with prader-willi are obese because of the fact that they simply never feel full. There is a place that specializes in Prader-willi somewhere in Florida. The best thing to do if you know someone who has Prader-willi syndromo is support them, they really do have to struggle every single day with diets. Watch the kitchen..i know it sounds inhumane but in the long run it is for the best for the person with prader-willi, remember they can literally eat themselves to death because they never feel full. And someone with prader-willi should do some sort of exercises or physical therapy because they do have very low muscle mass. I worked with someone who had prader-willi and this is what I know.

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
Prader-Willi Syndrome
Tay-Sachs is an autosomal (not sex linked) recessive disorder which has no effects at birth but leads to blindness, paralysis, mental retardation and death by three to four years of age.i have tay sachs and i am dead HAHA WORL SUK IT
Richard simmons.. believe it or not. That's why he does what he does
