What is Melo?
Melorheostosis is a rare and progressive bone disorder characterized by significant thickening of the cortical bone. It affects both bone and soft tissue growth and development. On x-rays, the appearance of melorheostosis has been likened to flowing, melted candle wax.


Our Mission
The Melorheostosis Association is a 501(c)(3) non-profit organization dedicated to finding the causes, treatments, and cures for melorheostosis. We focus on promoting greater awareness and understanding of this progressive disease and its manifestations through education, research, communication, and advocacy efforts on behalf of those affected by it as well as those dedicated to alleviating it.
About the Board
The Association is registered as a 501(c)(3) and is run by an all-volunteer board including a president, secretary, treasurer, and chairperson/founder. Board members plan conferences and events, foster communication between researchers and the patient community, and oversee fundraising efforts to support the patient community and ongoing research. A medical panel is in place to support the Association with best practices, research efforts, and patient advocacy in the rare disease space.
