- Abstract:
- We report on the fatal clinical course of a 3 year old male Turkish patient suffering from osteopetrosis caused by a homozygous mutation in the chloride channel gene ClCN7 with developing pancytopenia and severe neurological impairment. Hepatosplenomegaly due to extramedullary hematopoesis, severe transfusion-dependent anemia and growth failure initially suggested metabolic or oncologic disorder. Particular haematological parameters like tear drop cells basophilic punctation of the polymorphonuclear cells in the absence of haemolysis caused the diagnostic X-ray investigations of the skull and vertebral column. Raised serum creatinkinase-BB isoenzyme and genetic testing were in line with the diagnose of osteopetrosis at an age of 2(1/2) years. Osteopetrosis is a rare but considerable differential diagnose for unclarified change in haematopoetic cell lines combined with severe neurological symptoms mimicking metabolic or haematological disease. Because of this rare disease a consensus protocol for diagnostics, treatment and follow up of patients suffering from osteopetrosis is recently worked out from the European Group of Blood and Marrow Transplantation (EBMT) and the European Society for Immundeficiencies (ESID) to build up a central registry for this disease (available by ansgar.schulz@uniklinik-ulm.de).
