Disclaimer Osteopetrosis.org is a self-funded voluntary "signpost" site. We created it 10 years ago because most people diagnosed with OP had no place to begin the search for information and felt isolated. Thirty years ago little was known and even less was commonly available. Although much has been learned since then, most people diagnosed with OP still felt isolated and confused. We are not medical professionals. We do not give medical advice. All medical information presented should be discussed with a qualified physician.
