I have cherubism. I was diagnosed at age 3 and had the tumor surgically removed at age 13. Then I had implants placed for permanent teeth at age 20. Today I live normally. My main concern and reason for contact is: I'd like to know more about the cause of cherubism. How or why did I get it? There is no history in either of my families of cherubism. What are the signs and symptoms of cherubism? Do my future children run a strong risk? Can I be tested to see if I am a carrier? If I find that I am not a carrier can they still turn up with the disease? Is there prenatal testing available for cherubism. As you can see, I am mostly concerned for the future of my family. I do not have kids yet, but do plan to. See answer
