Angelman syndrome is a genetic disorder that causes developmental delay and neurological problems. Infants appear typical at birth but often have feeding problems and exhibit developmental delays by 6 to 12 months. Seizures often begin between 2 and 3 years of age. Speech impairment is pronounced. Individuals often display hyperactivity, small head size, sleep disorders, and movement and balance disorders. Angelman syndrome results from absence of a functional copy of the UBE3A gene inherited from the mother. There is no specific therapy for Angelman syndrome. Medical therapy for seizures is usually necessary. Physical and occupational therapies, communication therapy, and behavioral therapies are important in allowing individuals to reach their maximum developmental potential.
