Osteopetrosis autosomal dominant type 2
Type of disease: Rare conditions
Osteopetrosis is a bone disease that makes bones abnormally dense and prone to breakage (fracture). Researchers have described several major types of osteopetrosis, which are usually distinguished by their pattern of inheritance: autosomal dominant, autosomal recessive, or X-linked. The different types of the disorder can also be distinguished by the severity of their signs and symptoms. Mutations in at least nine genes cause the various types of osteopetrosis.
