The Williams Syndrome Foundation is a voluntary organisation run for parents, by parents.
Williams Syndrome is a rare disorder. Like Down syndrome it is caused by an abnormality in chromosomes, and shows a wide variation in ability from person to person. Williams People have a unique pattern of emotional, physical and mental strengths and weaknesses.
