Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.
Nonprofit support and advocacy groups bring together patients, families, medical professionals, and researchers. These groups often raise awareness, provide support, and develop patient-centered information. Many are the driving force behind research for better treatments and possible cures. They can direct people to research, resources, and services. Many groups also have experts who serve as medical advisors. Visit their website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
Living with a genetic or rare disease can impact the daily lives of patients and families. These resources can help families navigate various aspects of living with a rare disease.
These resources provide more information about this condition or associated symptoms. The in-depth resources contain medical and scientific language that may be hard to understand. You may want to review these resources with a medical professional.

International Meeting on Fibrous Dysplasia of Bone/McCune-Albright Syndrome: Best Clinical Practice and Future Research
Sunday, October 3, 2010 -
Tuesday, October 5, 2010
Location: NIH, Natcher Conference Center,
Bethesda,
Maryland
Description: The clinical scientists presented the results of their investigations and experience in the care of patients with fibrous dysplasia (FD) to the entire group for discussion and comment. At the end of the conference they came together in subgroups to define what is commonly held to be the best clinical practice. The scientists likewise presented their data for discussion and comment and came together to generate a roadmap for the focus of current and future research. It was also a goal to create greater collaboration between and among the clinical and basic scientists and the patient advocacy groups. One goal of the latter interaction was to promote the creation of a patient registry and tissue bank that will allow for the collection of standardized data on an international basis and make invaluable clinical material available to basic scientists.

My daughter who is 3 months old has a large cafe-au-lait lesion that has darkened since birth. It is very classical for this syndome (midline, coast of Maine, covers entire right buttocks and back of leg). We were referred to a pediatric dermatologist and she is being worked up for McCune Albright. The next step is a full series of x-rays. They are not sure taking them this early would show any bony changes. Do you have any recommendations of steps we can take now to determine if she does indeed have this syndrome and to what degree she is affected? See answer
What is the life expectancy? See answer
I was diagnosed with McCune Albright when I was 16. I was wondering the risks of pregnancy with McCune Albright? I am 20 now and already had 1 miscarriage. I want to know if this is possibly from my syndrome? See answer
Is McCune-Albright syndrome picked up by amniocentesis? I had an amniocentesis with my daughter and nobody told me she had it. See answer
Can you please provide some general information about McCune-Albright syndrome? See answer
