The Fibrous Dysplasia Support Society (FDSS) was formed in 2007 by a group of patients, and their carers, who are affected by Fibrous Dysplasia, McCune Albright Syndrome (MAS) or Cherubism. It exists to provide information and support by sharing our knowledge and experience of the condition with those who would like to know more. FDSS has no direct medical involvement or funding. It is currently funded by donations. These donations are then used to provide resources, and other activities such as meetings.
