A very rare condition that is similar to Treacher Collins syndrome is known as Miller or Wildervanck-Smith syndrome. Its characteristics include underdeveloped cheekbones, an abnormally small jaw, a cleft palate, small, protruding “cup-shaped” ears, and drooping of the lower eyelids. In addition, some children with the syndrome have incomplete development of one or more of the limbs, webbing of the fingers or toes, absence of the little fingers or toes, and underdevelopment of bones in the forearm. The condition does not, however, affect a child’s intelligence.
