What is International Angelman Day?

International Angelman Day (IAD) is observed on the 15th February to raise awareness worldwide for Angelman Syndrome (AS). Because this is such a rare disorder, we need everyone to help us spread the word. We want the whole world to know more about Angelman syndrome!  


Angelman Syndrome is  a rare neurogenetic disorder

that affects chromosome 15,

resulting in intellectual and developmental delay.

It affects about 1 in 15,000 people.


We celebrate each year on the 15th February in recognition of the 15th chromosome affected, and with February being International Rare Disease month.​

It is also the day after Valentine's Day, so its a good time to spread the love...
















Families and organisations all around the world

are invited to join us as we unite to commemorate

this special day, each year.
