Gaucher disease, the most common lysosomal storage disorder, is due to a deficiency in the enzyme glucocerebrosidase. This leads to the accumulation of its normal substrate, glucocerebroside, in tissue macrophages, affecting the hematological, visceral, bone and neurologic systems. Gaucher disease is classified into three broad phenotypes based upon the presence or absence of neurological invol...

The lysosomal enzyme glucocerebrosidase, encoded by the glucocerebrosidase gene, is involved in the breakdown of glucocerebroside into glucose and ceramide. Lysosomal build-up of the substrate glucocerebroside occurs in cells of the reticulo-endothelial system in patients with Gaucher disease, a rare lysosomal storage disorder caused by the recessively inherited deficiency of glucocerebrosidase...

Gaucher disease is a rare, hereditary disease caused by lack of a lysosomal enzyme. This results in the accumulation of glucocerebroside in the cells of the reticuloendothelial system, including the bone marrow. The orthopaedic manifestations of this disease are important for the orthopaedic surgeon to recognize and understand. Patients with Gaucher disease are at risk for pathologic fracture, ...

Absruact. An 8-month-old Sydney Silky dog that was ataxic and hyperkinetic was found to have a neurovisceral storage disease. Typical Gaucher cells were seen in the liver, lymph nodes and cerebellum, but not in the spleen. Ultrastructurally, the storage bodies in Gaucher cells contained tubular structures, and many neurones contained laminated cytosomes, accumulations of a ‘wispy’ material and ...

This paper describes a neonate with type II Gaucher disease. The phenotype was unusually severe with congenital ichthyosis, hepatosplenomegaly, muscular hypotonia, myoclonus and respiratory failure. Electron microscopy of the skin revealed lamellar body contents in the stratum corneum interstices, appearances considered to be typical of type II Gaucher disease. The baby died from respiratory fa...

OBJECTIVE To study the clinical and biochemical spectrum of Gaucher disease. DESIGN Assay of beta glucosidase enzyme in leucocytes in patients with splenomegaly, and in chorionic villi for prenatal diagnosis. SETTING Hospital-based. SUBJECTS Of 13 cases of Gaucher disease, aged 1-6 years, 9 were identified at Delhi and 4 at Bombay. RESULTS The enzyme beta-glucosidase was 0.65 nmol/h/mg ...

Gaucher disease is a progressive lysosomal storage disorder caused by the deficiency of glucocerebrosidase, and characterized by intralysosomal storage of glucosylceramide that leads to dysfunction in multiple organ systems. Intravenous enzyme replacement with imiglucerase is the accepted standard for treatment of symptomatic patients and has been effective in reducing many of the signs and sym...

Gaucher disease is due to mutations involving the glucocerebrosidase gene. A closely homologous pseudogene is located approximately 16 kD downstream from the functional gene. Sequence analysis of clones from cDNA libraries made from skin fibroblast cultures showed several independent clones with the sequence of an aberrantly processed pseudogene message. Examination of cellular RNA from lymphob...

In mammalian cells, glucosylceramide (GlcCer), the simplest glycosphingolipid, is hydrolyzed by the lysosomal enzyme acid beta-glucosidase (GlcCerase). In the human metabolic disorder Gaucher disease, GlcCerase activity is significantly decreased owing to one of approximately 200 mutations in the GlcCerase gene. The most common therapy for Gaucher disease is enzyme replacement therapy (ERT), in...
