Affected individuals often are tall, slender and loose-jointed. Arms and legs may be unusually long in proportion to the torso. Feet often are flat. The spine may be curved (scoliosis), and the breastbone may protrude or look caved in. The face may be long and narrow, with a high roof of the mouth and crowded teeth. Sorry for the Vanity, but J. F'ing Kerry sure looks like he fits the profile.
