Angelman syndrome: is there a characteristic EEG?

Am J Med Genet Mar 2: Reserpine responsive myoclonus and hyperpyrexia in a patient with Angelman syndrome. Jerky, tremulous, or dystonic movements proved to be a cortical myoclonus, defined by video-EEG and polygraphic monitoring. The consistent findings include: The facial features and general physical examination are generally normal, although a protruding tongue, strabismus, brisk deep tendon reflexes, and a happy demeanor may be present.

Eg is more common in those individuals who have the deletion subtype of the syndrome. Hypopigmentation in infants with AS due to deletion of the P pigment gene but may be overlooked.
