What You Should Know About Angelman Syndrome

Last update: 11 October, 2015

On several occasions I have reflected on the way that our work serves a higher purpose. Humbly and honestly I have to say that I am lucky to be able to use the “power of the pen” to raise awareness of current news and interesting information that can help people. Among all of you thousands of people that read our articles and who we have so much gratitude toward for giving us your time and attention, there are surely many of you that know someone affected by what we are about to discuss.

Using that ultimate power of words to awaken people’s conscience, lift broken hearts and lost spirits, today we would like to let you know about a little-known syndrome called “Angelman syndrome (AS)” or “Happy puppet syndrome.”

Testimony is the best way to raise awareness

Aitor was 20 months old when his parents were told he would never walk… they still were not aware that he had AS. Now he is 6 years old and we can read about his life on the Facebook page his parents have created called “The Adventures and Misadventures of a Family with Angelman.” And, he plays soccer, plays the drums, loves swimming, running, and playing on the computer and adores his brother Urko.

Angelman Syndrome

In 1965 the English pediatrician Harry Angelman was the first to describe this syndrome. He recognized that 3 of his patients had the same characteristics: severe intellectual disability, motor speech deficits, and excessive laughter. It was 30 more years until it was discovered in 1987 that these people lacked a fragment of DNA on chromosome 15.

10 things you should know about the happy puppet syndrome

  1. It affects very few people. In Spain there are barely 250 known cases, although there are surely more, because doctors who are not very familiar with a syndrome may confuse it for other disorders like autism or cerebral palsy.
  2. Newborns with AS are completely normal and do not exhibit signs of slow neurological development (including motor skills) until six months of age. These signs become more prominent after the first year.
  3. Sixty percent of those affected by AS have blonde hair and blue eyes because of hypopigmentation.
  4. They have below average head circumference (microcephaly)
  5. Characteristic facial features include: prominent jaw, wide mouth, sunken eyes, and a tendency to stick their tongue out.
  6. They also often experience: severe speech impediment, tremors in the limbs, seizures…
  7. Always with a happy disposition and constant laughter, they earned the nickname “happy puppet” from the pediatrician Harry Angelman in 1965.
  8. Each case is unique and in 15% of cases the cause is still unknown.
  9. The risk of having a second child with Angelman Syndrome is very high.
  10. It is possible through a prenatal diagnosis using chorionic villus sampling or amniocentesis to identify 85% of cases.
