Prader-Willi Syndrome         Prader-Willi syndrome (PWS) is a genetic dis methodicalness that causalitys low muscle stones retch (floppiness), short stature, cognitive disabilities (mental retardation), behavioural problems, and chronic hunger that dope lead to over-eating and life sonorous obesity. The discommode is unremarkably peed by an error during sperm and clump abidanceation, non passed on from hold dear to child like or so genetic sicknesss. This makes the disease intimately impossible to mention in the p atomic number 18nts (only 5% of the time) (Cassidy). The disorder is considered rare, only if occurs in 1 out of any 14,000 people, making it the most joint genetic disorders, and the most harsh genetic produce of obesity.         The disorder is linked with the 15th chromosome, in a diminished slit labeled 15q11-q13. Scientists do not bed exactly how more genes and which specific ones are involved, provided they do k outright the cause of the abnormalities.         70% of all cases of PWS are caused by maternal(p) deletion. This makes it the most vernacular form of the disorder. The cause is; cancel of chromosome 15 transmittable from the father (the part containing the PWS vituperative genes) is missing. typic deletions are now classified as fibre 1 or fictional character 2, depending on the size. Deletion happens for seemingly no reason, and has a less(prenominal) 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 chromosome 15 are inherited from the pay back (hence, Uniparental). In these cases, the developing conceptus starts out with terzetto copies of chromosome 15, because the mothers glob had an limited one. Later, one of the three is lost (the fathers), and has the same solution as deletion. When the whole chromosome is deleted, it usually leads to other genetic disorders as well.         5% of cases are caused...
