Short answer · Medically reviewed summary · Last updated: 2026-05-08
Fibrodysplasia ossificans progressiva (FOP), historically known as "Stone Man’s Disease," was first formally described in the 17th century by Guy Patin, who documented a patient whose muscles turned to bone. Today, we understand Fibrodysplasia ossificans progressiva as a rare genetic condition caused by a mutation in the ACVR1 gene, which leads to heterotopic ossification—the transformation of soft tissue into bone. When was Fibrodysplasia ossificans progressiva first described? While reports date back to the 1600s, the first comprehensive clinical description of Fibrodysplasia ossificans progressiva is often attributed to John Freke in 1740.
What is the history of Fibrodysplasia ossificans progressiva?
History of Fibrodysplasia ossificans progressiva: when and how it was discovered, and the milestones in research since, medically reviewed.
Fibrodysplasia ossificans progressiva (FOP), historically known as "Stone Man’s Disease," was first formally described in the 17th century by Guy Patin, who documented a patient whose muscles turned to bone.

When was Fibrodysplasia ossificans progressiva first described?
While reports date back to the 1600s, the first comprehensive clinical description of Fibrodysplasia ossificans progressiva is often attributed to John Freke in 1740. For centuries, the condition was shrouded in medical mystery and often misdiagnosed as cancer, leading to tragic outcomes where surgeons attempted to remove the bone growths, only to trigger even more aggressive ossification.
How has our understanding of FOP evolved?
The greatest leap in understanding Fibrodysplasia ossificans progressiva occurred in 2006, when researchers identified the ACVR1 gene mutation. Before this, the condition was poorly understood, often leading to invasive biopsies that exacerbated the patient's condition. Modern imaging and genetic testing have replaced these dangerous historical practices, allowing for earlier, non-invasive diagnosis.
What are the major milestones in research?
The journey toward managing Fibrodysplasia ossificans progressiva has shifted from purely palliative care to targeted molecular research. Key milestones include:
- 2006: Discovery of the ACVR1 mutation by Dr. Eileen Shore and colleagues.
- 2010s: Initiation of global natural history studies to better track the progression of Fibrodysplasia ossificans progressiva.
- Recent Years: Clinical trials focusing on retinoic acid receptor gamma (RARγ) agonists to inhibit abnormal bone formation.
How has patient advocacy shaped the field?
The patient community has been instrumental in driving research. Organizations like the IFOPA have empowered families to connect, share data, and participate in clinical trials. Within the DiseaseMaps.org community, 49 people with Fibrodysplasia ossificans progressiva have joined to share their lived experiences, proving that collective patient data is as vital as clinical research in navigating this rare disease.
