Summaries for SOST Gene

Entrez Gene Summary for SOST Gene

  • Sclerostin is a secreted glycoprotein with a C-terminal cysteine knot-like (CTCK) domain and sequence similarity to the DAN (differential screening-selected gene aberrative in neuroblastoma) family of bone morphogenetic protein (BMP) antagonists. Loss-of-function mutations in this gene are associated with an autosomal-recessive disorder, sclerosteosis, which causes progressive bone overgrowth. A deletion downstream of this gene, which causes reduced sclerostin expression, is associated with a milder form of the disorder called van Buchem disease. [provided by RefSeq, Jul 2008]

GeneCards Summary for SOST Gene

SOST (Sclerostin) is a Protein Coding gene. Diseases associated with SOST include sclerosteosis 1 and craniodiaphyseal dysplasia, autosomal dominant. Among its related pathways are TGF-beta Signaling Pathway (sino) and Wnt signaling pathway (KEGG). GO annotations related to this gene include transcription factor binding and heparin binding. An important paralog of this gene is SOSTDC1.

Disorders for SOST Gene

(3) OMIM Diseases for SOST Gene (605740)


  • Sclerosteosis 1 (SOST1) [MIM:269500]: An autosomal recessive sclerosing bone dysplasia characterized by a generalized hyperostosis and sclerosis leading to a markedly thickened skull, with mandible, ribs, clavicles and all long bones also being affected. Due to narrowing of the foramina of the cranial nerves, facial nerve palsy, hearing loss and atrophy of the optic nerves can occur. Sclerosteosis is clinically and radiologically very similar to van Buchem disease, mainly differentiated by hand malformations and a large stature in sclerosteosis patients. {ECO:0000269 PubMed:11179006, ECO:0000269 PubMed:11181578, ECO:0000269 PubMed:20583295}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Van Buchem disease (VBCH) [MIM:239100]: 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. {ECO:0000269 PubMed:11836356}. Note=The disease is caused by mutations affecting the gene represented in this entry. A 52 kb deletion downstream of SOST results in SOST transcription suppression causing van Buchem disease.
  • Craniodiaphyseal dysplasia autosomal dominant (CDD) [MIM:122860]: A severe bone dysplasia characterized by massive generalized hyperostosis and sclerosis, especially involving the skull and facial bones. The sclerosis is so severe that the resulting facial distortion is referred to as leontiasis ossea (leonine faces) and the bone deposition results in progressive stenosis of craniofacial foramina. Respiratory obstruction due to choanal stenosis compromises the clinical outcomes of affected patients. {ECO:0000269 PubMed:21221996}. Note=The disease is caused by mutations affecting the gene represented in this entry. Heterozygous mutations located in the secretion signal of the SOST gene prevent sclerostin secretion and can be responsible for craniodiaphyseal dysplasia.
