Prader-Willi syndrome is a rare genetic disorder that can develop in infancy and eventually affect many body parts and systems by childhood. Infants with Prader-Willi syndrome may have poor muscle tone and difficulties in feeding. In childhood, individuals with the disorder will have have an overactive appetite and experience problems with chronic overeating, leading to quick weight gain and obesity.
Other symptoms of Prader-Willi syndrome can include learning disabilities, underdeveloped genitals (in both male and female patients), and short stature. It is estimated that Prader-Willi syndrome affects one in every 15,000 children.
