The OIF has been critical in the development of the infrastructure of this network, the design of the clinical trials, the establishment of a patient contact registry, and the support of two of the 8 clinical sites. Since 1970 the Osteogenesis Imperfecta Foundation has been providing support to people living with OI and those trying to find cures and treatments for the disorder. The Foundation’s principal education event is the Biennial National Conference on OI, which in 2008 provided more than 750 people with medical, research and coping information. This year as part of the OI conference, a delegation of conference attendees visited Capitol Hill and visited 44 congressional offices in an effort to educate them about OI and priorities of the Foundation.
