Osteopetrosis is a disorder involving defective bone resorption [1]. Two main forms of osteopetrosis have been delineated: a severe autosomal recessive form with an incidence of 1 in 250,000 births and a mild autosomal dominant form with an incidence of 1 in 20,000 births [1]. Intrinsic disturbances of osteoclast function due to mutations in genes encoding osteoclast–specific subunits of the vacuolar proton pump are found in most patients [1].
