BACKGROUND Gaucher disease (GD) is an autosomal recessive lysosomal storage disorder caused by deficiency in acid beta-glucosidase. GD exhibits a wide clinical spectrum of disease severity with an unpredictable natural course. Plasma chitotriosidase activity and CC chemokine ligand 18 (CCL18) have been exchangeably used for monitoring GD activity and response to enzyme replacement therapy in co...

In Gaucher disease type I (GD, OMIM #230800), deficient activity of the enzyme glucocerebrosidase results in hepatosplenomegaly, cytopenia and skeletal disease. Skeletal disease leads to chronic bone pain and/or severe complications such as pathological fractures, avascular necrosis and bone crises. Enzyme Replacement Therapy symptoms of the disease with doses ranging between 15 and 120 U/kg/4w...

BACKGROUND Gaucher disease (GD) is a rare recessively inherited disorder caused by deficiency of a lysosomal enzyme, glucocerebrosidase. Accumulation of glucosylceramide or glucosylsphingosine in macrophages leads to increased production of ferritin and chitotriosidase and to decreases in hemoglobin concentration and platelet count, which are used as blood biomarkers. GD is treated by enzyme re...

Farber disease caused by acid ceramidase deficiency is characterised by a triad of painful and swollen joints, subcutaneous nodules, and laryngeal involvement. A one year old female with overlapping features of the classical and type 5 variants is reported. Sialuria and elevated plasma chitotriosidase were unusual findings. A novel mutation of the ASAH 1 gene was detected from DNA extracted fro...

Background: Cystinosis is a rare autosomal recessive lysosomal storage disease with high morbidity and mortality. It caused by mutations in the CTNS gene that encodes cystine transporter, cystinosin, which leads to accumulation. major cause of inherited Fanconi syndrome, should be suspected young children failure thrive signs renal proximal tubular damage. The diagnosis can missed infants, beca...

OBJECTIVE Gaucher's disease is a rare genetic disorder that results in the accumulation of cerebrosides in the liver, spleen, kidneys, lungs, brain and bone marrow. The deficiency of the specific lysosomal enzyme glucocerebrosidase is considered as causative factor. The first effective treatment for the disease, the drug Ceredase, approved in 1995, was replaced in 2001 by the drug Cerezyme®. ...

Human Glyco_18 domain-containing proteins constitute a family of chitinases and chitinase-like proteins. Chitotriosidase and AMCase are true enzymes which hydrolyse chitin and have a C-terminal chitin-binding domain. YKL-40, YKL-39, SI-CLP and murine YM1/2 proteins possess solely Glyco_18 domain and do not have the hydrolytic activity. The major sources of Glyco_18 containing proteins are macro...
