Glucocerebrosidase activity in Parkinson's disease with and without GBA mutations.
Glucocerebrosidase (GBA) mutations have been associated with Parkinson's disease in numerous studies. However, it is unknown whether the increased risk of Parkinson's disease in GBA carriers is due to a loss of glucocerebrosidase enzymatic activity. We measured glucocerebrosidase enzymatic activity in dried blood spots in patients with Parkinson's disease (n = 517) and controls (n = 252) with a...
متن کاملInteraction between parkin and mutant glucocerebrosidase variants: a possible link between Parkinson disease and Gaucher disease.
Gaucher disease (GD), a sphingolipidosis characterized by impaired activity of the lysosomal enzyme glucocerebrosidase (GCase), results from mutations in the GCase-encoding gene, GBA. We have shown that mutant GCase variants present variable degrees of endoplasmic reticulum (ER) retention and undergo ER-associated degradation (ERAD) in the proteasome. Furthermore, the degree of ERAD of mutant G...
متن کاملGlucocerebrosidase Mutations in Parkinson Disease.
Following the discovery of a higher than expected incidence of Parkinson Disease (PD) in Gaucher disease, a lysosomal storage disorder, mutations in the glucocerebrocidase (GBA) gene, which encodes a lysosomal enzyme involved in sphingolipid degradation were explored in the context of idiopathic PD. GBA mutations are now known to be the single largest risk factor for development of idiopathic P...
متن کاملGlucocerebrosidase 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 کامل-Glucocerebrosidase activity in mammalian stratum corneum
Although previous studies have demonstrated a crucial role for the enzyme b -glucocerebrosidase (GlcCer’ase) in the final steps of membrane structural maturation in mammalian stratum cornuem (SC) and epidermal homeostasis, the precise in vivo localization of GlcCer’ase activity and protein is not known. Here, we developed a fluorogenic in situ assay on histologic sections (zymography) to elucid...
