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 is the most common cause of FOP?

FOP is caused by a mutation in the ACVR1 gene. This gene is involved in growth and development of bones. The mutation allows them to grow unchecked. The gene can be inherited from one parent, but in most cases of FOP, it’s a new mutation in a person with no family history of the disease.

At what age can you get FOP?

The HO in FOP normally presents between birth and 26 years of age, with presentation in the first decade being the most common. There are a few case reports of patients presenting with FOP in their late forties, but age 54 is the oldest presentation reported in the literature to date [9].
