Associations of Monocyte Glucocerebrosidase with Cognition and Cholinergic Innervation in GBA1 Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background The GBA1 gene encodes the lysosomal enzyme glucocerebrosidase (GCase). Parkinson's disease (PD) patients carrying a GBA1 variant (GBA‐PD) exhibit faster cognitive decline, linked to cholinergic degeneration. Objectives The aim was to investigate whether GCase activity, measured in monocytes, correlates with cognitive dysfunction or ...

Biomarkers of Leucine‐Rich Repeat Kinase 2 (LRRK2) and Lysosomal Dysfunction in Progressive Supranuclear Palsy

Movement Disorders, EarlyView.
Abstract Background Common and rare genetic variants in leucine‐rich repeat kinase 2 (LRRK2) have been linked with sporadic and familial Parkinson's disease (PD). Recently, we discovered that common genetic variation near the LRRK2 locus determined survival in progressive supranuclear palsy (PSP).

The Global Parkinson's Disease Genetics (GP2) Genome Browser

Movement Disorders, EarlyView.
Abstract Background Large‐scale sequencing initiatives have generated extensive genomic resources essential for variant interpretation, yet their effective use often requires bioinformatics expertise. To support identification of Parkinson's disease (PD) risk and disease‐causing variants, we developed an open‐access, summary‐level genomic data browser.

Co‐ and Multi‐Pathologies in Parkinson's Disease: An International Parkinson and Movement Disorder Society Scientific Issues Committee Review

Movement Disorders, EarlyView.
Abstract Parkinson's disease (PD) has been historically defined as a disease of striatal dopamine deficiency secondary to degeneration of dopaminergic neurons in the substantia nigra pars compacta, related to the presence of Lewy bodies and Lewy neurites.

Clinical, mechanistic, biomarker, and therapeutic advances in GBA1-associated Parkinson’s disease

Translational Neurodegeneration
Parkinson’s disease (PD) is the second most common neurodegenerative disease. The development of PD is closely linked to genetic and environmental factors, with GBA1 variants being the most common genetic risk.

Dual-Risk axis: mutations and occupational pesticide exposure in Parkinson's disease

Journal of Parkinson’s Disease
Background Occupational pesticide (OcP) exposure and pathogenic GBA1 variants are established risk factors for Parkinson's disease (PD). However, whether they interact to influence disease onset or severity remains uncertain.

Gaucher disease: single gene molecular characterization of one-hundred Indian patients reveals novel variants and the most prevalent mutation

BMC Medical Genetics, 2019
Background Gaucher disease is a rare pan-ethnic, lysosomal storage disorder resulting due to beta-Glucosidase (GBA1) gene defect. This leads to the glucocerebrosidase enzyme deficiency and an increased accumulation of undegraded glycolipid ...

Heterogenous Neuropathology in a Pedigree with RAB39B‐Related Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background In 2015, we reported a family with Parkinson's disease resulting from the RAB39B p.G192R (c.574G>A) variant. Since then, two affected brothers from the family have undergone autopsy. Objectives To characterize neuropathological findings, assess intracellular distribution of RAB39B protein, and examine the effect of p.G192R on α ...

Novel heterozygous c.798C>G and c.1040T>G mutations in the GBA1 gene are associated with a severe phenotype of Gaucher disease type 1 [PDF]

Annals of Hematology, 2014
Dear Editor, Gaucher disease (GD) is a progressive, multisystem, autosomal recessive lysosomal storage disorder caused by the deficient activity of the lysosomal enzyme, glucocerebrosidase, arising from mutations in the GBA1 gene (1q21) [1]. Hematological symptoms, such as thrombocytopenia or splenomegaly, are frequent disclosing signs of GD type 1 (

Electroencephalography‐Based Clustering Reveals Robust Neurophysiological Subtypes in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Parkinson's disease (PD) is clinically heterogeneous, with substantial variability in motor and cognitive features. Conventional clinical scales provide limited insight into underlying neural mechanisms and show poor longitudinal stability.
