    This is a complex syndrome that affects the nervous system. There is usually mental retardation, speech deficits, seizures and small head size. Weirdly many of these people are blond. They tend to be happy, excitable kids who often mouth objects and flap their hands.

    It is usually caused by an inactive gene inherited from the mother. Normally each parent has a copy of a certain gene. When the mother's copy is inactive, then Angelman's will be evident.
