SOST-related sclerosing bone dysplasia is a disorder of bone development characterized by excessive bone formation (hyperostosis). As a result of hyperostosis, bones throughout the body are denser and wider than normal, particularly the bones of the skull. Affected individuals typically have an enlarged jaw with misaligned teeth. People with this condition may also have a sunken appearance of the middle of the face (midface hypoplasia), bulging eyes with shallow eye sockets (ocular proptosis), and a prominent forehead. People with this condition often experience headaches because increased thickness of the skull bones increases pressure on the brain. The excessive bone formation seen in this condition seems to occur throughout a person's life, so the skeletal features become more pronounced over time. However, the excessive bone growth may only occur in certain areas.
MalaCards based summary
:
Van Buchem Disease, also known as
hyperostosis corticalis generalisata, is related to
sclerosteosis 2 and
hyperostosis, and has symptoms including
constipation,
seizures and
vomiting. An important gene associated with Van Buchem Disease is
SOST (Sclerostin), and among its related pathways/superpathways are
Wnt signaling pathway and
Signaling by Wnt. Affiliated tissues include
bone,
eye and
brain, and related phenotypes are
facial palsy and
mandibular prognathia

Van Buchem disease is an autosomal recessive bone dysplasia characterized by a symmetrically increased thickness of bones, most frequently found as an enlarged jawbone, but also an enlargement of the skull, ribs, diaphysis of long bones, as well as tubular bones of hands and feet, resulting in increased cortical bone density. The clinical consequences of increased thickness of the skull include facial nerve palsy causing hearing loss, visual problems, neurologic pain, and very rarely, blindness resulting from optic atrophy. Bone anomalies appear in the first decade of life and progress with age (summary by Wergedal et al., 2003).

Van Buchem disease: VBCH is an autosomal recessive sclerosing bone dysplasia characterized by endosteal hyperostosis of the mandible, skull, ribs, clavicles, and diaphyses of the long bones. Affected patients present a symmetrically increased thickness of bones, most frequently found as an enlarged jawbone, but also an enlargement of the skull, ribs, diaphysis of long bones, as well as tubular bones of hands and feet. The clinical consequence of increased thickness of the skull include facial nerve palsy causing hearing loss, visual problems, neurological pain, and, very rarely, blindness as a consequence of optic atrophy. Serum alkaline phosphatase levels are elevated.

Clinical manifestations include increased skull thickness with cranial nerve entrapment causing inconsistent cranial nerve palsies.Visit the Orphanet disease page for more resources.

A hyperostosis that has material basis in a mutation in the SOST gene which results in overgrowth of endosteal bone producing dense and wide bones throughout the body especially located in skull.
