AS is a rare genetic neuro-developmental disorder characterized by severe developmental delay, sleep disorders, jerky movements and frequent laughter .

It was first discovered in the year 1965 by a British Pediatrician, Dr. Harry Angelman.

The syndrome is caused by an abnormality in a region of chromosome 15 and it’s usually not recognized at birth.

AS is typically diagnosed between the ages of 3 and 7.

The main characteristics of this syndrome are delayed motor skills, minimal or absence of speech, developmental delay, ataxia (shaky and unsteady movements), seizures, constant happy behavior that includes frequent laughing, smiling and excitability.

The exact prevalence of AS is unknown, but it is estimated that it affects 1 in 12000-20000 people.
