What causes FOP disease?
FOP is caused by the mutation of a gene (ACVR1) in the bone morphogenetic protein (BMP) pathway, which is important during the formation of the skeleton in the embryo and the repair of the skeleton following birth.
What disease causes extra bone growth?
Fibrodysplasia ossificans progressiva is a disorder in which muscle tissue and connective tissue such as tendons and ligaments are gradually replaced by bone (ossified), forming bone outside the skeleton (extra-skeletal or heterotopic bone) that constrains movement.
How is FOP treated?
Currently, there is no cure for FOP. Courses of high-dose corticosteroids at the start of a flare-up can reduce some of the symptoms of the condition.
How is FOP diagnosed?
The diagnosis of FOP is made by clinical evaluation. Confirmatory genetic testing is available. Differential diagnosis includes progressive osseous heteroplasia, osteosarcoma, lymphedema, soft tissue sarcoma, desmoid tumors, aggressive juvenile fibromatosis, and non-hereditary (acquired) heterotopic ossification.
What are the symptoms of FOP disease?
Symptoms of FOP include:
- malformations of the big toe.
- spontaneous flare-ups of inflammation or soft tissue swelling.
- increased flare-ups after injury, viral illness, or immunizations.
- difficulty moving.
- frequent injury due to falling.
What are the symptoms of FOP?
Fibrodysplasia Ossificans Progressiva (FOP)
- Episodes of muscle swelling and inflammation followed by rapid ossification after trauma to a muscle.
- Difficulty speaking and eating as mouth becomes affected.
- Malformed big toes present at birth: This abnormality often helps distinguish FOP from other musculoskeletal conditions.

The mannequins have similar weight distribution to a human.
Why were mannequins used in nuclear tests?
During the 1950s, mannequins were used in nuclear tests to help show the effects of nuclear weapons on humans.
Do mannequins weigh the same as humans?
The mannequins have similar weight distribution to a human. Special obese mannequins and horse mannequins have also been made for similar purposes.
