FD/MAS Alliance works to resolve the many points of isolation and disconnection caused by FD/MAS’s rarity by serving as an accessible, collaborative, and supportive hub for information and action. 

FD/MAS Global Awareness Week is a coordinated international campaign to raise awareness of fibrous dysplasia and McCune-Albright syndrome (FD/MAS) and build support for public health and research that will improve the lives of FD/MAS patients.

We honor this week starting on February 20th in recognition of the mutation that leads to FD and MAS, which occurs on the 20th chromosome. We ask you and your community to contribute $20 because we believe that, when we come together, we can advance new research, open up new treatment options, spark new hope, and improve the lives of those affected by FD/MAS.

When you become a supporter of the FD/MAS Alliance, you will help answer once and for all the many questions left about this rare disease.
