Description : Craniodiaphyseal dysplasia is a severe bone dysplasia characterized by massive generalized
hyperostosis and sclerosis, especially involving the skull and facial bones. Progressive
bony encroachment upon cranial foramina leads to severe neurologic impairment in childhood
(summary by Brueton and Winter, 1990). The sclerosis is so severe that the resulting
facial distortion is referred to as 'leontiasis ossea' (leonine facies), and the bone
deposition results in progressive stenosis of craniofacial foramina (summary by Kim
et al., 2011).;
Inheritance : Autosomal dominant;
Molecular basis : Caused by mutation in the sclerostin gene (SOST, 605740.0005);
