Glucocerebrosidase mutations in Gaucher disease.
BACKGROUND Thirty-six mutations that cause Gaucher disease, the most common glycolipid storage disorder, are known. Although both alleles of most patients with the disease contain one of these mutations, in a few patients one or both disease-producing alleles have remained unidentified. Identification of mutations in these patients is useful for genetic counseling. MATERIALS AND METHODS The D...
متن کاملGlucocerebrosidase processing in normal fibroblasts and in fibroblasts from patients with type I, type II, and type III Gaucher disease.
Fibroblasts from normal subjects and patients with the three types of Gaucher disease were labeled with [3H]leucine. Glucocerebrosidase antigen was immunoprecipitated using affinity-purified Sepharose-bound antibody. Normal cells initially formed a 60-kDa polypeptide antigen that was gradually replaced by a broad band of antigen averaging 63 kDa. This position corresponds with that of mature fi...
متن کاملHydrophilic iminosugar active-site-specific chaperones increase residual glucocerebrosidase activity in fibroblasts from Gaucher patients.
Gaucher disease is an autosomal recessive lysosomal storage disorder caused by the deficient activity of glucocerebrosidase. Accumulation of glucosylceramide, primarily in the lysosomes of cells of the reticuloendothelial system, leads to hepatosplenomegaly, anemia and skeletal lesions in type I disease, and neurologic manifestations in types II and III disease. We report herein the identificat...

ITCH regulates degradation of mutant glucocerebrosidase: implications to Gaucher disease.
Inability to properly degrade unfolded or misfolded proteins in the endoplasmic reticulum (ER) leads to ER stress and unfolded protein response. This is particularly important in cases of diseases in which the mutant proteins undergo ER-associated degradation (ERAD), as in Gaucher disease (GD). GD is a genetic, autosomal recessive disease that results from mutations in the GBA1 gene, encoding t...
