International Angelman Day – February 15, 2025

Every year, International Angelman Day (I.A.D.) is observed on February 15 to create awareness about Angelman Syndrome, a neurogenetic disorder affecting chromosome 15 that causes intellectual and developmental delays. Angelman Syndrome is a rare disorder occurring in one out of 15,000 babies. It affects males and females equally. The name originated with English pediatrician Harry Angelman, who initially referred to the condition of three of his patients as “Puppet Children.” Today, over 490,000 people live with Angelman Syndrome worldwide. You can show your support by checking out community resources and wearing blue angel wings or ribbons.

History of International Angelman Day

Harry Angelman first discovered the neurogenetic disorder Angelman Syndrome at Warrington General Hospital in 1956. Although the condition had no name at the time, the symptoms in each person were similar; motor disorders, intellectual delay, a happy demeanor, and lack of speech. Angelman visited the Castelvecchio Museum in Verona during a trip to Italy and discovered a painting by Giovanni Francesco Caro called, ‘A boy with the puppet.’ As he looked at the artistic impression, images of his patients came to mind, which led him to write an article about their condition entitled “Puppet Children.”

There was little data on the condition until 1982. Dr. Charles Williams and Dr. Jaime Frias of the Department of Pediatrics at the University of Florida College of Medicine, Gainesville, successfully submitted a paper to the American Journal of Medical Genetics describing six patients and comparing their results to previous reports. The report included symptoms similar to those described by Angelman, including severe developmental delay, a puppet-like gait, craniofacial abnormalities, and frequent laughter. Thus, Williams and Frais proposed the disorder be named Angelman Syndrome.

Williams founded the Angelman Research Group (A.R.G.) to facilitate and support research and education concerning Angelman Syndrome in 1986. By 1990, the A.R.G. had formed the Angelman Syndrome Foundation. Two parents with children suffering from Angelman Syndrome came up with the idea for International Angelman Day. National Angelman Syndrome organizations worldwide accepted this idea, and the unanimous date of February 15 was agreed on. The first commemoration of this day was in 2013.
