Angelman syndrome (AS) is a genetic disorder primarily affecting the nervous system. Key characteristics include distinctive facial features, developmental delays, intellectual disabilities, speech impairment, motor difficulties, and seizures. Despite these challenges, individuals with AS often exhibit a cheerful disposition and a fascination with water. Symptoms typically manifest within the first year of life.
Around 1964, Angelman encountered three children with distinct disabilities in England, yet he sensed an underlying commonality in their conditions.
Despite lacking scientific evidence, Angelman published his observations of the three children in 1965, calling them "Puppet Children". The name was later changed to Angelman syndrome.
Harry Angelman, inspired by a painting titled "...a Boy with a Puppet" observed jerky movements in his patients, leading him to use the term "Puppet Children" to categorize them in his 1965 publication.
In 1965, British pediatrician Harry Angelman provided the first medical description of Angelman syndrome, bringing it to the attention of the medical community.
A breakthrough occurred in 1987 when researchers discovered that approximately half of the children diagnosed with AS exhibited a partial deletion on chromosome 15 (chromosome 15q partial deletion), providing crucial genetic insight into the syndrome.
In 1995, a significant step towards understanding and diagnosing Angelman syndrome was taken with the establishment of the initial diagnostic criteria, developed in collaboration with the Angelman Syndrome Foundation (US).
Reflecting advancements in the understanding of Angelman syndrome, the diagnostic criteria were revisited and revised in 2005, aiming for greater accuracy and clarity.
The Filipino drama series "Budoy," aired in 2011, featured a main character, Budoy Maniego, diagnosed with Angelman syndrome, raising awareness and understanding of the condition among a wider audience.
