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.

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 ...

A collection of integration-free iPSCs derived from Parkinson's disease patients carrying mutations in the GBA1 gene

Stem Cell Research, 2019
Mutations in the GBA1 gene, which encodes the lysosomal enzyme Glucocerebrosidase1 are major risk factors for Parkinson's disease (PD) and dementia with Lewy bodies (DLB).

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.

The GBA1 p.E427K (p.E388K) Variant Is a Risk Factor for Synucleinopathies: A Meta‐Analysis

Movement Disorders, EarlyView.
Abstract Background Variants in GBA1 are important genetic risk factors for synucleinopathies, including Parkinson's disease (PD). Although several GBA1 variants are established risk or severity modifiers, the role of the p.E427K variant remains unclear.

Rare‐Variant Burden across Lysosomal Genes Implicates Sialylation and Ganglioside Metabolism in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Lysosomal dysfunction is central to Parkinson's disease (PD) pathogenesis, with GBA1 representing the strongest established genetic risk factor. Numerous other genes involved in lysosomal sphingolipid, glycosphingolipid, and ceramide metabolism have been proposed as contributors to PD, highlighting the need for genetic analyses ...

GBA1 as a risk gene for osteoporosis in the specific populations and its role in the development of Gaucher disease

Orphanet Journal of Rare Diseases
Background Osteoporosis and its primary complication, fragility fractures, contribute to substantial global morbidity and mortality. Gaucher disease (GD) is caused by glucocerebrosidase (GBA1) deficiency, leading to skeletal complications.

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.

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 ...
