Autosomal dominant endosteal hyperostosis is a generalized bone dysplasia characterized by a cortical thickening of the long bones, with no alteration in external shape, and a remarkable resistance of the bone to fracture. The skeleton is normal in childhood. Facial metamorphoses occur in adolescence, as the forehead flattens, the mandible becomes elongated, and the gonial angle decreases. An enlarging osseous prominence (torus palatinus) develops in the hard palate, which may lead to malocclusion or loss of teeth (summary by Van Wesenbeeck et al., 2003).

Brain abnormalities, neurodegeneration, and dysosteosclerosis (BANDDOS) is an autosomal recessive disorder characterized by brain abnormalities, progressive neurologic deterioration, and sclerotic bone dysplasia similar to dysosteosclerosis (DOS). The age at onset is highly variable: some patients may present in infancy with hydrocephalus, global developmental delay, and hypotonia, whereas others may have onset of symptoms in the late teens or early twenties after normal development. Neurologic features include loss of previous motor and language skills, cognitive impairment, spasticity, and focal seizures. Brain imaging shows periventricular white matter abnormalities and calcifications, large cisterna magna or Dandy-Walker malformation, and sometimes agenesis of the corpus callosum (summary by Guo et al., 2019).
