Overview Fibrodysplasia Ossificans Progressiva (FOP)

Fibrodysplasia ossificans progressiva, also known as myositis ossificans progressiva or MOP, is a disabling condition, which is caused by the formation of bony bars within the muscles of the body.

This disorder occurs in all countries in the world and affects about one person in a million. Men and women seem to be equally affected.

What is the life-span of people who have FOP?

General health remains good and several people with FOP in Britain are over 60 years old.  In view of the reduced chest expansion respiratory tract infections need to be treated vigorously.
