Alpha‐synuclein RT‐QuIC assay in gastroduodenal and skin biopsies of Parkinson disease patients
Abstract In this study, we compared the value of pathological alpha‐synuclein (αSyn) seed amplification assay (SAA) in gastric and duodenal biopsies with skin biopsies in Parkinson disease (PD) patients with different disease duration. The accuracy of αSyn SAA was 87.7% in skin, 67.4% in duodenum, and 80.0% in gastric biopsies, with significantly ...

Calcium modulating ligand confers risk for Parkinson's disease and impacts lysosomes
Abstract Objective Several genetic loci known to confer risk for Parkinson's disease (PD) function in lysosomal pathways. We systematically screened common variants linked to PD risk by genome‐wide association studies (GWAS) for impact on cerebrospinal fluid (CSF) proteins reflecting lysosomal function.

Relationship of cognitive decline with glucocerebrosidase activity and amyloid‐beta 42 in DLB and PD
Abstract Objective Dementia with Lewy bodies (DLB) and Parkinson's disease (PD) share clinical, pathological, and genetic risk factors, including GBA1 and APOEε4 mutations. Biomarkers associated with the pathways of these mutations, such as glucocerebrosidase enzyme (GCase) activity and amyloid‐beta 42 (Aβ42) levels, may hold potential as predictive ...

Blood exosome connexins and small RNAs related to demyelinating disease activity
Abstract Objectives To assess blood exosome (Ex)‐connexin (Cx)43 (encoded by GJA1) and its truncated isoforms in multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD), which show distinct alterations in astroglial Cx43. Methods Serum Exs from 48 patients with MS (34 relapsing–remitting, 14 secondary‐progressive), 35 with NMOSD, 20 ...

Novel pathogenic mtDNA variants in Chinese children with neurological mitochondrial disorders
Abstract Objective Pathogenic variations in the mitochondrial genome are tightly linked to neurological mitochondrial disorders in children. However, the mutation spectrum of mitochondrial DNA (mtDNA) in the Chinese population remains incomplete. Therefore, the primary objective of our study was to comprehensively characterize pathogenic mtDNA variants

ALS plasma biomarkers reveal neurofilament and pTau correlate with disease onset and progression
Abstract Objective We performed a pilot screen to assess the utility of the NULISA™ (Nucleic‐acid‐Linked Immuno‐Sandwich Assay) platform in the identification of amyotrophic lateral sclerosis (ALS) biomarkers. Methods Plasma from 86 individuals (48 ALS, 18 asymptomatic C9orf72 repeat expansion carriers (AsymC9), and 20 healthy controls) was analyzed ...

Targeted Long‐Read Sequencing as a Single Assay Improves the Diagnosis of Spastic‐Ataxia Disorders
ABSTRACT Objective The hereditary spastic‐ataxia spectrum disorders are a group of disabling neurological diseases. The traditional genetic testing pathway is complex, multistep and leaves many cases unsolved. We aim to streamline and improve this process using long‐read sequencing. Methods We developed a targeted long‐read sequencing strategy with the
