Occurrence of Parkinson's syndrome in type I Gaucher disease.

Augmentation of phenotype in a transgenic Parkinson mouse heterozygous for a Gaucher mutation.

The involvement of the protein α-synuclein (SNCA) in the pathogenesis of Parkinson's disease is strongly supported by the facts that (i) missense and copy number mutations in the SNCA gene can cause inherited Parkinson's disease; and (ii) Lewy bodies in sporadic Parkinson's disease are largely composed of aggregated SNCA. Unaffected heterozygous carriers of Gaucher disease mutations have an inc...

Report of Four Children with Gaucher Disease and Review of Literature

Gaucher Disease (GD) is the most common type of Lysosomal Storage Disorder and it is divided into three distinct subtypes. The authors here report four different cases of Gaucher Disease, with varying clinical manifestations, and the diagnosis of each established by the low level of Beta-Glucosidase enzyme as well as genetic DNA testing. The study also highlights the importance of early diagnos...

A Feedforward Loop Links Gaucher and Parkinson's Diseases?

Mutations in the GBA gene that encodes glucocerebrosidase cause the lysosomal storage disorder Gaucher disease but also increase the risk for Parkinson's disease. Mazzulli et al. (2011) uncover a possible mechanism to explain this connection: loss of glucocerebrosidase creates a positive feedback loop of reduced lysosomal function and α-synuclein accumulation, ultimately leading to neurodegener...

A Case of Gaucher\'s Disease with Recurrent Fetal Loss and Antiphospholipid Antibody Syndrome

A clinical and family history study of Parkinson's disease in heterozygous glucocerebrosidase mutation carriers

Type I Gaucher disease (GD), the most common lysosomal storage disorder, is caused by recessive glucocerebrosidase mutations. Both patients with Type I GD and heterozygous glucocerebrosidase mutation carriers have increased Parkinson’s disease (PD) risk. Non-motor symptoms (NMS) are more frequent in PD with heterozygous glucocerebrosidase mutations (PD-GBA). We used the non-motor symptoms scale...
