Angelman syndrome = paternal imprinting or paternal UPD. Prader-Willi syndrome is a rare genetic disorder that was first described by Andrea Prader, Heinrich Willi, and Alexis Labhart in 1956. 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), 786-596-1960. 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) In short, imprinting of the same region on chromosome 15 has been implicated for both Angelman and Prader-Willi syndromes.
