title: Hypomandibular faciocranial dysostosis: another case and review.
abstract: We report on a third case of hypomandibular faciocranial dysostosis and review the literature. Manifestations include craniosynostosis, prominent eyes, deficient midface and zygomatic arches, short nose with anteverted nares, protruding lower face, minute oral aperture, persistent buccopharyngeal membrane, and severe mandibular hypoplasia. In contrast to coronal synostosis found in the 2 earlier cases, our patient had multiple sutural synostosis. The 2 affected sibs reported earlier suggest the possibility of autosomal recessive inheritance. However, gonadal mosaicism for a dominant mutation or an undetected microdeletion must also be considered at this early stage in the delineation of this disorder.
