FD/MAS Alliance

The FD/MAS Alliance, incorporated as The Fibrous Dysplasia Foundation, is dedicated to leading the fight against fibrous dysplasia and McCune-Albright syndrome (FD/MAS), rare and complex bone and endocrine diseases. Through programs focused on research, education, and support, we aim to improve the lives of those affected by FD/MAS. We are committed to advancing scientific knowledge, raising awareness, and providing vital resources for patients and families while advocating for better treatments and outcomes for this underserved community. Together, we strive to make a difference in the lives of those living with FD/MAS.
