Robin Sequence: More Than a Receding Chin
By John Mulliken, MD, Director, Craniofacial Centre, Boston Children’s Hospital
Children born with Robin sequence (named for an early 20th century French physician; pronounced row-BAN) have a lower jaw that is smaller than normal (micrognathia) or set back from the upper jaw (retrognathia).
Stickler syndrome is the basis for about 40 percent of infants with Robin sequence. It is a disorder of the body's collagen -- the tissue that connects the bones, heart, eyes, and ears. It generally occurs in infants with no family history of the condition.
