FD/MAS Alliance, Patiëntenvereniging Fibreuze Dysplasie, ASOCIACIÓN DE DISPLASIA FIBROSA – ADF, Fibrous Dysplasia Support Society UK, and European Association for McCune-Albright Syndrome are announcing the launch of the International Consortium for Fibrous Dysplasia and McCune-Albright syndrome Ltd. (ICFDMAS). 

Fibrous dysplasia and McCune-Albright syndrome (FD|MAS) is a rare disease that can cause a wide range of issues. It is genetic, but it is not inherited from family and cannot be passed down. It can be traced to a single random mutation that occurs in the womb as a fetus develops. Symptoms range from mild to severe, and people living with FD|MAS can live full and prosperous lives. There is no cure, however, and there are no treatments to stop or slow a major symptom of the disease, the growth of malformed bones. These malformed bones cause chronic pain, weak bones that are easy to fracture, and differently-shaped bodies. Patients turn to a range of stopgap treatments, like multiple surgeries, hormonal therapeutics, and medical device implants to try and manage their disease.

The mission of the International Consortium for FD/MAS is to improve the care and find solutions for the unmet needs of patients and their carers through the promotion of multi-stakeholder, collaborative, and patient-centric clinical, translational, and basic research. The International Consortium for FD/MAS will encourage  the testing and development of potential cures and treatments. Also it will promote the development of evidence-based standards of care. The consortium aims to improve access to information worldwide through dissemination and education initiatives. Finally the consortium will  support the development of cooperative scientific studies and initiatives with promise to serve the global FD/MAS patient community. 

Already, the ICFDMAS has published “Best practice management guidelines for fibrous dysplasia/McCune-Albright syndrome” in Orphanet Journal of Rare Diseases and led to 5 collaborative research publications. In addition to a host of international patient advocacy organizations involved, researchers from the National Institutes of Health, Leiden University in the Netherlands,University Claude Bernard-Lyon in France, Sapienze University of Rome in Italy and University of Oxford, England are also involved.

In honor of FD/MAS Global Awareness Week (20-27th February) the ICFDMAS has launched a website complete with resources and information for patients, caregivers, and clinicians.
