Gene Therapy for Parkinson’s Disease Associated with Mutations

Journal of Parkinson’s Disease, 2021
Human genetic studies as well as studies in animal models indicate that lysosomal dysfunction plays a key role in the pathogenesis of Parkinson’s disease.

Deregulation of mTORC1-TFEB axis in human iPSC model of GBA1-associated Parkinson’s disease

Frontiers in Neuroscience, 2023
Mutations in the GBA1 gene are the single most frequent genetic risk factor for Parkinson’s disease (PD). Neurodegenerative changes in GBA1-associated PD have been linked to the defective lysosomal clearance of autophagic substrates and aggregate-prone ...

Freezing of gait in Parkinson’s disease with glucocerebrosidase mutations: prevalence, clinical correlates and effect on quality of life

Frontiers in Neuroscience, 2023
ObjectivesMutations in glucocerebrosidase (GBA1) can change the clinical phenotype of Parkinson’s disease (PD). This study aimed to explore the clinical characteristics of freezing of gait (FOG) in PD patients with GBA1 mutations.MethodsA whole-exome ...

Lack of full sequencing GBA1 studies for patients with Parkinson’s disease in Latin America

npj Parkinson's Disease, 2022
Full sequencing of the GBA1 gene in patients with Parkinson’s disease provides a wide screening of pathogenic variants, but less developed regions of the world, like Latin America, may have difficulties in performing full sequencing.

Glucocerebrosidase activity, cathepsin D and monomeric α-synuclein interactions in a stem cell derived neuronal model of a PD associated GBA1 mutation

Neurobiology of Disease, 2020
The presence of GBA1 gene mutations increases risk for Parkinson's disease (PD), but the pathogenic mechanisms of GBA1 associated PD remain unknown. Given that impaired α-synuclein turnover is a hallmark of PD pathogenesis and cathepsin D is a key enzyme

Accurate long-read sequencing identified GBA1 as major risk factor in the Luxembourgish Parkinson’s study

npj Parkinson's Disease, 2023
Heterozygous variants in the glucocerebrosidase GBA1 gene are an increasingly recognized risk factor for Parkinson’s disease (PD). Due to the GBAP1 pseudogene, which shares 96% sequence homology with the GBA1 coding region, accurate variant calling by ...

Decreased glucocerebrosidase activity and substrate accumulation of glycosphingolipids in a novel GBA1 D409V knock-in mouse model.

PLoS ONE, 2021
Multiple mutations have been described in the human GBA1 gene, which encodes the lysosomal enzyme beta-glucocerebrosidase (GCase) that degrades glucosylceramide and is pivotal in glycosphingolipid substrate metabolism.

and The Immune System: A Potential Role in Parkinson’s Disease?

Journal of Parkinson’s Disease, 2022
It is clear that the immune system and inflammation have a role in Parkinson’s disease (PD), including sporadic PD and some genetic forms such as LRRK2 -associated PD.

Mutational spectrum and clinical features of GBA1 variants in a Chinese cohort with Parkinson’s disease

npj Parkinson's Disease, 2023
GBA1 variants are important risk factors for Parkinson’s disease (PD). Most studies assessing GBA1-related PD risk have been performed in European-derived populations.

GBA1 in Parkinson’s disease: variant detection and pathogenicity scoring matters

BMC Genomics, 2023
Background GBA1 variants are the strongest genetic risk factor for Parkinson’s disease (PD). However, the pathogenicity of GBA1 variants concerning PD is still not fully understood.
