Angelman syndrome (AS) is a neurological disorder in which severe learning difficulties are associated with a characteristic facial appearance and behavior. An older, alternative term for this syndrome, happy puppet syndrome, is generally considered pejorative and stigmatizing and is no longer in current use.
History
Dr. Harry Angelman, a pediatrician working in Warrington, Cheshire, first reported three children with this condition in 1965. It was initially presumed to be rare. In 1987, it was first noted that around half of the children with Angelman syndrome have a small piece of chromosome 15 missing chromosome 15q partial deletion. Since this time the condition has been reported more frequently and the incidence is now thought to be 1 in 25,000 children.
Pathophysiology
Angelman syndrome is caused by the loss of the normal maternal contribution to a region of chromosome 15, most commonly by deletion of a segment of that chromosome. Other causes include uniparental disomy, translocation, or single gene mutation in that region. A healthy person receives two copies of chromosome 15, one from mother, the other from father. However, in the region of the chromosome that is critical for Angelman syndrome, the maternal and paternal contribution express certain genes very differently. This is due to sex-related epigenetic imprinting; the biochemical mechanism is DNA methylation. If the maternal contribution is lost or mutated, the result is Angelman syndrome. (When the paternal contribution is lost, by similar mechanisms, the result is Prader-Willi syndrome.) More on [ Angelman syndrome ]
