New clinical findings in the Richieri-Costa/Pereira type of acrofacial dysostosis.

The Richieri-Costa/Pereira form of acrofacial dysostosis is an autosomal-recessive condition characterized by short stature, Pierre-Robin sequence, preaxial and postaxial abnormalities in hands, congenital talipes, cleft mandible and malformations of the larynx. We report female infant presenting with severe micrognathia, a hypoplasic clavicle, median mandible cleft, bilateral hand abnormalities and talipes, laryngeal malformations, hip subluxation with acetabular dysplasia and mesomelic shortening of limbs. A few reported patients have clavicular hyploplasia but hip subluxation with acetabular dysplasia and mesomelic shortening of limbs have not been described.
