A Case of Angelman Syndrome / 대한소아신경학회지

ABSTRACT

Angelman syndrome is a rare genetic disorder characterized by developmental delay, speech impairment, ataxic gait, paroxysmal laughter, and seizures. The diagnosis is suspected in infants who have the characteristic clinical features and electroencephalographic (EEG) abnormalities, and is confirmed by the genetic identification of a maternally derived 15q11-13 deletion. We report a case of genetically confirmed Angelman syndrome who had the characteristic clinical and EEG features.
