A rare, syndromic intellectual disability characterized by severe intellectual deficit, brachycephaly, plagiocephaly, and prominent forehead in male patients. Females may display moderate intellectual deficit without craniofacial dysmorphism. There have been no further descriptions in the literature since 1992. |

A rare genetic dysostosis disorder with characteristics of craniofacial bone abnormalities (for example midface hypoplasia, broad, flat nasal bridge, narrow, thin prognathic mandible with pointed chin, malocclusion, partial dental agenesis) associated with additional osseous anomalies, including scoliosis, calvarial thinning, pointed spinous processes, clinodactyly and abnormal phalanges. Elevated erythrocyte sedimentation rate, hyperuricemia and hypertension have also been reported. There have been no further descriptions in the literature since 1982. |

A rare genetic bone development disorder characterized by occipital and parietal bone hypoplasia leading to occipital encephalocele, calvarial mineralization defects, craniosynostosis, radiohumeral fusions, oligodactyly and other skeletal anomalies (arachnodactyly, terminal phalangeal aplasia of the thumbs, bilateral absence of the great toes, pronounced bilateral angulation of femora, shortened limbs, advanced osseous maturation). Fetal death in utero is associated. There is evidence the disease can be caused by homozygous mutation in the CYP26B1 gene on chromosome 2p13. |

A rare genetic developmental defect during embryogenesis disorder with characteristics of craniofacial dysmorphism (including brachycephaly, prominent forehead, sparse lateral eyebrows, severe hypertelorism, upslanting palpebral fissures, epicanthal folds, protruding ears, broad nasal bridge, pointed nasal tip, flat philtrum, anteverted nostrils, large mouth, thin upper vermilion border, highly arched palate and mild micrognathia) associated with osteopenia leading to repeated long bone fractures, severe myopia, mild to moderate sensorineural or mixed hearing loss, enamel hypoplasia, sloping shoulders and mild intellectual disability. There is evidence the disease can be caused by homozygous mutation in the IRX5 gene on chromosome 16q11.2. |

A rare genetic multiple congenital anomalies/dysmorphic syndrome characterized by congenital cataract, sensorineural hearing loss, developmental delay with variable degrees of intellectual disability, seizures, short stature, brachycephaly, and dysmorphic facial features (such as flat facial appearance, ptosis, short nasal tip, long philtrum, low-set and posteriorly rotated ears, and small mouth). Additional reported manifestations are skeletal abnormalities, nail dystrophy, mammary gland hypoplasia, and autism spectrum disorder. |

A syndromic craniosynostosis with a wide range of clinical findings even within a single family. Most have coronal synostosis however synostosis of other sutures, all sutures, macrocephaly without craniosynostosis, or a normal skull may be observed. Bilateral coronal synostosis usually results in brachycephaly with temporal bossing and facial symmetry. Craniofacial findings include widely spaced eyes, ptosis or proptosis, strabismus, and high arched palate or cleft lip/palate. Over 70% of patients have some form of hearing loss. Additional extracranial manifestations include otitis media, brachydactyly, broad toes, broad thumbs, clinodactyly, developmental delay and intellectual disability. Caused by mutation in the FGFR3 gene (4p16.3), encoding fibroblast growth factor receptor 3, which is required for normal skeleton development. Inheritance is autosomal dominant. |

A rare primary bone dysplasia with increased bone density characterized by slowly progressive endosteal hyperostosis and osteosclerosis exclusively of the skull base and the calvaria, resulting in entrapment and dysfunction of cranial nerves I, II, V, VII, and VIII. First symptoms often appear during the second decade of life and include disturbances in smell, vision, facial sensation and expression, hearing, and balance, as well as headaches due to increased ocular and intracranial pressure. After the fourth decade, radiological progression is minimal, although decreased intracranial volume can lead to death in severe cases. |
