Web12 apr. 2024 · Introduction. Deleterious mutations in GBA, the gene for the lysosomal glucocerebrosidase (GCase), are the cause of Gaucher disease (GD) but are also the most common genetic risk factor for the neurodegenerative disorder Parkinson's disease (PD). 1-3 PD represents the most frequent synucleinopathy, 4 and reduction of α-synuclein … WebLoss of lysosomal glucocerebrosidase (GCase) activity contributes to the development of both Gaucher disease and Parkinson disease. GCase is of high interest due to its potential as both a therapeutic target and diagnostic marker. However, an inability to accurately measure GCase activity within lysosomes is hindering progress.
