In 1956, when the medical world first learned slightly Prader-Willi syndrome, doctors had no idea what caused people to have this collection of features and problems that we straightaway know as PWS. It is only in the last 20 years that researchers have discovered the genetic changes that are obligated for the syndrome.

PWS is attributed to a spontaneous genetic error that occurs at or near time of conception for unknown reasons. The incidence of this syndrome is 1/10,000- 1/25,000 live affinitys. Occurring in both sexes and all races. Although considered a rare disorder, Prader-Willi Syndrome is one of the most common conditions seen in genetic clinics, and is the most common genetic cause of obesity that has been identified.

The natural event of PWS is due to the lack of several genes on one of an individuals 2 chromosome 15s, the one normally contributed by the father. In the majority of the cases, in that location is a deletion of chromosome 15; the critical genes are in some manner lost from the chromosome. Deletion happens for no known reason, and it is not in all probability to happen in another pregnancy.

PWS is not usually an communicable condition; it just happens.

Clinical features begin during the gestational period. 1) Reduced foetal activity (76%), 2) Nonterm delivery (41%), and 3) Breech presentation (26%). During infancy, Gross aim developgenial delay (98%), infantile decreased muscle tone (94%), feeding difficulties with or without failure to thrive (93%), and low birth weight (30%), present themselves. Neurological manifestations may include mental retardation (97%), skin picking (79%), personality problems (41%), and seizures (20%). Endocrine manifestations can include, undersized...
