If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.
If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

All the information I've seen on Gardner syndrome is about polyps; I can't find anything about bony growth in this condition. I have a bony growth in my neck that is completely surrounding a nerve. Where can I find information and help about this? See answer
I was diagnosed with Gardner syndrome at birth. I had a total colectomy with illeoanal reservoir. Since the surgery, I have had several orthopedic issues with my spine and shoulder which cause my joints to be extremely flexible, often resulting in catastrophic problems from a minor injury. I also have had two spinal issues, so at the age of 30 I am looking at permanent pain management therapy as a possibility. I also have days where I am just completely out of gas by about 1 pm or can't go to work. My dad's side of the family is the same way - we all have this disorder. Is all this related to Gardner syndrome? See answer
My mother-in-law has been diagnosed with Gardner syndrome. How is this syndrome inherited? Is there a genetic test to find out if my wife, and eventually our children are affected with Gardner syndrome? See answer
