Abstract
Anthropometric methods were used to examine 18 males 18 to 69 years old with the Fragile-X syndrome. Thirteen of 15 subjects had macroorchidism. The average height of the individuals with the Fragile-X was less than that of published standards. Seventeen of the 18 subjects had absolute or relative macrocephaly, and two-thirds of the subjects were dolichocephalic. For the group as a whole, facial and ear lengths were increased, and facial breadth, hand length, and foot length were decreased. It is suggested that relationships between various measurements of an individual may be more important than any single measurements for conveying the characteristic appearance of an individual with the Fragile-X syndrome.
