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
