Fibrodysplasia ossificans progressiva is a rare and severely debilitating genetic disorder affecting approximately 1 in 2 million people. It is characterized by progressive heterotopic ossification of soft tissues, leading to the formation of ectopic bone in extraskeletal areas, as well as congenital malformations of the great toes. FOP can also be considered a disorder of osteochondrogenesis, with most musculoskeletal abnormalities related to dysregulated chondrogenesis, such as heterotopic endochondral ossification, abnormal cartilage formation, growth plate dysplasia, osteochondroma formation, and early arthropathy.
