    What are the genetic changes related to SOST-related sclerosing bone dysplasia ?
    ### Response:
    SOST-related sclerosing bone dysplasia is caused by mutations in or near the SOST gene. The SOST gene provides instructions for making the protein sclerostin. Sclerostin is produced in osteocytes, which are a type of bone cell. The main function of sclerostin is to stop (inhibit) bone formation.
