What are the effects of osteopetrosis?

Is there a treatment for Sclerosteosis?

There are no specific treatments for sclerosteosis and VBD. The management of the diseases aims to surgical correction of syndactyly, decompression of cranial nerves and reduction of mandibular overgrowth.

Where does osteopetrosis occur?
