Journey to Discovery: A Breakthrough Built on Hope

Introducing a new video series produced by the IFOPA that revisits the extraordinary story behind the FOP gene discovery and celebrates the 20th anniversary of this turning point in our shared journey.

Launching March 31 on the IFOPA's YouTube channel.

The journey to an accurate FOP diagnosis can be exhausting and overwhelming.

On average, a family will visit three specialists before receiving an FOP diagnosis — and some will see up to 10. They have to travel from specialist to specialist, spending significant time and money in their desperate search for answers.

A misdiagnosis can be even costlier. Procedures like diagnostic biopsies and surgeries not only waste time and money but can also trigger flare-ups, speeding up the progression of FOP.

Since FOP is an ultra-rare disease, many doctors are not familiar with its early symptoms or have never encountered a patient with FOP, leading to dangerous misdiagnosis and improper care.

What is fibrodysplasia ossificans progressiva (FOP)?

One of the rarest, most disabling genetic conditions known to medicine, fibrodysplasia ossificans progressiva (FOP) causes bone to form in muscles, tendons, ligaments and other connective tissues. Bridges of extra bone develop across joints, progressively restricting movement and forming a second skeleton that imprisons the body in bone. There are no other known examples in medicine of one normal organ system turning into another.

When a misdiagnosis can lead to irreversible damage, the stakes are high.

That’s why the IFOPA is committed to partnering with the medical community to provide informed care, spread awareness, build an interconnected network of resources and advance the search for treatments and a cure.
