Abstract:

BACKGROUND: Low incidence of hereditary multiple exostoses leads to few lines for clinical research, and difficulty in duplicating cellular and animal models delay the studies on the pathogenesis.
OBJECTIVE: To summarize the research progress of pathological changes, molecular mechanisms and signaling pathways of hereditary multiple exostoses.
METHODS: By consulting relevant researches at home and abroad and researching the genetic website, we integrated related content and opinions.
RESULTS AND CONCLUSION: (1) Hereditary multiple exostoses are an autosomal dominant hereditary skeletal disease characterized by multiple bone neoplasms covered by cartilages that grow outward from the metaphysis of long tubular bones. The clinical symptoms that are related to factors such as location, size and shape are variable. (2) The disease is genetically heterogeneous and is mainly associated with mutations in the tumor suppressor genes Exostosin-1 or Exostosin-2 of the EXT family. The occurrence of the disease is mainly associated with heparin sulfate and its downstream signaling pathways in the molecular level. (3) We have summarized the researches on hereditary multiple exostoses in the past decades and paved the way for future investigation.
