A 16-year-old male patient with type II autosomal dominant benign osteopetrosis (ADO) was genotyped and found to harbor a novel mutation in exon 25 of the gene encoding for the osteoclast-specific chloride channel, CLCN7, inherited from the father, who was asymptomatic. The patient had normal biochemical findings and acid-base balance, except for increased serum levels of creatine kinase, lactic dehydrogenase, and the bone formation markers bone alkaline phosphatase isoenzyme, osteocalcin and N-terminal type I collagen telopeptide/creatinine ratio. Unusual generalized osteosclerosis was observed together with a canonical increase in vertebral and pelvis bone mass. An affected first grade cousin presented with normal biochemical findings and a milder osteosclerotic pattern of the pelvis. At the cellular level, cultured osteoclasts from the patient showed increased motility, with lamellipodia, membrane ruffling and motile pattern of podosome distribution, all of which could have contributed to functional impairment of bone resorption. The present report documents a novel mutation of the CLCN7 gene causing osteopetrosis in a radiologically uncertain form of the diseases, with apparent incomplete penetrance.
