Mandibulofacial dysostosis with microcephaly (MFDM) is characterized by malar and mandibular hypoplasia; microcephaly (congenital or postnatal onset); malformations of the pinna, auditory canal, and/or middle ear (ossicles and semi-circular canals) with associated conductive hearing loss; and distinctive facial features (metopic ridge, up- or downslanting palpebral fissures, prominent glabella, broad nasal bridge, bulbous nasal tip, and everted lower lip). Associated craniofacial malformations may include cleft palate, choanal atresia, and facial asymmetry. Intellectual disability is a prominent feature. Major extracranial malformations include: esophageal atresia (~40%), congenital heart disease (~40%), and thumb abnormalities (~25%). Short stature is present in approximately one third of individuals. [from GeneReviews]
