The goal of this research study is to identify genes and regulatory elements on chromosomes that cause cherubism. Together with the investigators collaborators the investigators also study blood samples and tissue samples from patients to learn about the processes that lead to this disorder. The long-term goal of researchers involved in this study is to find mechanisms to slow down bone resorption in cherubism patients.
Cherubism is a very rare bone disorder where bone gets excessively resorbed only in the jaw bones (mandible and maxilla). The resulting cavities in bone fill up with soft fibrous (fibro-osseous) tissues that can expand and push the bony shells apart. Thus the characteristic facial appearance in patients with progressed cherubism. Bone resorption (cherubism lesions) in this disorder occurs always symmetrically in the mandible, the maxilla or in both. This distinguishes cherubism from similar disorders. As cherubism progresses, the lesions can invade the eye sockets (inferior and/or lateral orbi…
