Sometimes life's greatest gifts come from the most unexpected sources. With humor, insight and emotion, Elizabeth Higgins Clark reflects on what she has been given by her brother, David, who has Fragile X syndrome.

Fragile X is the most common form of genetically transferred intellectual disability. Clark gave the following speech in Danbury, Connecticut at the 11th Annual Fall X Ball benefitting the FRAXA Research Foundation.

FRAXA asked Clark to give this speech after her piece on Ann Coulter's use of the "R word" made the front page of The Huffington Post.
