Fibrous dysplasia of bone (FD) is a crippling skeletal disease caused by activating mutations (R201C, R201H) of the Gsα gene. We recently generated GsαR201C transgenic mice that develop a FD skeletal phenotype. The analyses of these mice demonstrated that increased bone resorption is one of the main morbidity factors in FD and that RANKL is the major molecular mediator of osteolysis at affected skeletal sites.Ob...

Fibrous dysplasia (FD) is a benign skeletal disease caused by activating mutations of Gsα. These mutations lead to formation of abnormal and mechanically unsound bone and fibrotic tissue. Clinical sequelae include deformity, fracture, and pain. Studies in bisphosphonates have shown improvement in bone pain and inconsistent effects on FD mineralization; however interpretation has been limited by a lack of controlled trials.Objecti...
