Camptodactyly-joint contractures-facial skeletal defects syndrome is characterised by the association of camptodactyly, multiple eye defects (fibrosis of the medial rectus muscle, severe myopia, ptosis and exophthalmos), scoliosis, flexion contractures and facial anomalies (arched eyebrows, facial asymmetry with an abnormal skull shape, a prominent nose, small mouth, low-set and dysplastic ears, and a low nuchal hairline).

Distance between the commissures of the mouth more than 2 SD below the mean. Alternatively, an apparently decreased width of the oral aperture (subjective).
