What causes Fibrous dysplasia ?
What causes fibrous dysplasia? The cause of fibrous dysplasia has been linked to a gene mutation that occurs after conception, in the early stages of fetal development. The mutation involves a gene that affects the cells that produce bone. People with fibrous dysplasia carry this mutation in some, but not all cells of their body. It is not well understood why the mutation occurs, but it is not inherited from a parent, nor can it be passed on to future offspring.
