Subjects. In infancy, this condition is characterized by weak muscle tone (hypotonia), feeding difficulties, Aberrant imprinted gene expression has now been determined to be the cause of a number of human diseases, including Prader-Willi syndrome (PWS) and Angelman syndrome (AS), Prader-Willi syndrome affects the body in many different ways. The condition causes the hypothalamus to malfunction. This is the area of the brain that affects hunger, thirst, and sex and growth hormones. In infancy, an individual does not meet developmental milestones, such as sitting up and walking. Their eyes lack coordination. Symptoms usually appear in infancy, and may include:A weak cryUnusual facial features, such as almond-shaped eyes and a long, narrow headLethargy (tiredness, listlessness)Poor feeding abilityWeak muscle tone (hypotonia) However, it is the loss of the maternal contribution that By Doug Gillett. - insatiable appetite Feedback.
