Miller postaxial acrofacial dysostosis. The phenotypic changes with age.

We report data on the clinical and psychological follow-up of a boy with Miller postaxial acrofacial dysostosis syndrome between the ages of 1 and 7 years. After an initial psychomotor retardation intellectual and social function improved significantly after the use of hearing aids (50-70 db bilateral hearing loss). The facial appearance changed with age: the face became asymmetric and triangular with more pronounced ectropion and fine, thin lips.
