Timing of Deep Brain Stimulation and Cognitive Trajectories in GBA1-Associated Parkinson's Disease.

BACKGROUND Individuals with Parkinson's disease (PD) carrying GBA1 variants often develop advanced motor complications that prompt evaluation for deep brain stimulation (DBS). However, concerns about accelerated cognitive decline after DBS in GBA1 carriers complicate clinical decision making. A critical aspect that is...

The Effect of LRRK2 and GBA1 Mutations on Survival in Early- and Late-Onset Parkinson's Disease.

BACKGROUND Mutations in the glucocerebrosidase 1 (GBA1) and leucine-rich repeat kinase 2 (LRRK2) genes are associated with Parkinson's disease (PD) phenotype. OBJECTIVE To asses the contribution of genetic status to long-term survival of patients with PD. METHODS A total of 2039 PD patients with Ashkenazi ancestry...

Genome-wide association studies identify genetic determinants of synucleinopathy biomarkers

Background α-Synucleinopathies are clinically and biologically heterogeneous disorders lacking reliable biomarkers to assist with early diagnosis, disease progression, patient stratification, and therapeutic targeting. Genetic variation is known to impact biomarker levels, influencing their utility and interpretation i...

GCH1 genetic variation as a prognostic factor in Parkinson disease across populations

GCH1 pathogenic variants were associated with a clinically distinct phenotype characterized by earlier disease onset and slower progression of motor complications, suggesting that GCH1 genetic variants may serve as genetic biomarkers for patient stratification and prognosis in PD.

Large-scale functional annotation establishes a reference framework for human LRRK2 variants

Functional effect sizes correlated with pathway activation in patient-derived immune cells, altogether providing a framework for ACMG-based variant interpretation in which kinase activation can support PS3 functional evidence for reclassification of variants.
