Prader-Willi Syndrome         Prader-Willi syndrome (PWS) is a genetic dis methodicalness that causalitys low muscle stones slough (floppiness), short stature, cognitive disabilities (mental retardation), behavioral problems, and chronic hunger that mess lead to over-eating and life threatening obesity. The disorder is usually prepared by an error during sperm and testicle abidanceation, non passed on from shelter to child like or so genetic unsoundnesss. This makes the disease intimately impossible to detect in the p atomic number 18nts (only 5% of the time) (Cassidy). The disorder is considered rare, only if occurs in 1 out of all 14,000 people, making it the most leafy vegetable genetic disorders, and the most earthy genetic cause of obesity.         The disorder is linked with the 15th chromosome, in a diminished section labeled 15q11-q13. Scientists do not bed exactly how many genes and which specific ones are involved, neverth eless they do know the cause of the abnormalities.         70% of all cases of PWS are caused by maternal(p) deletion. This makes it the most common form of the disorder. The cause is; cancel of chromosome 15 inherited from the father (the part containing the PWS unfavorable genes) is missing. typic deletions are now classified as geek 1 or Type 2, depending on the size. Deletion happens for on the face of it no reason, and has a less than 1% chance of recurring).

        25% of cases are cause by Maternal uniparental disomy. This less common form of PWS happens when both copies of c hromosome 15 are inherited from the come (h! ence, Uniparental). In these cases, the developing embryo starts out with three copies of chromosome 15, because the mothers egg had an limited one. Later, one of the three is lost (the fathers), and has the same kernel as deletion. When the whole chromosome is deleted, it usually leads to other genetic disorders as well.         5% of cases are caused...
