Additional facial features include an abnormally small distance from the upper lip to the nose (short philtrum), incomplete closure of the roof of the mouth (cleft palate), an abnormal groove or gap in the upper lip (cleft lip), and abnormal fullness of the lower lip. In addition, the fleshy mass (uvula) that hangs in the back of the throat may be spilt (bifid uvula). As affected infants age the face may lose its plumpness and become abnormally long and narrow.
