Abstract Background Parkinson's disease (PD) is a neurodegenerative with an often complex component identifiable by genome‐wide association studies. The most recent large‐scale PD studies have identified more than 90 independent risk variants for and progression across 80 genomic regions. One major challenge in current genomics the identification of causal gene(s) variant(s) at each study locus. objective was to create tool that would display data relevant loci provide guidance...

Rapid-eye movement (REM) sleep behavior disorder (RBD), enactment of dreams during REM sleep, is an early clinical symptom alpha-synucleinopathies and defines a more severe subtype. The genetic background RBD its underlying mechanisms are not well understood. Here, we perform genome-wide association study RBD, identifying five risk loci near SNCA, GBA, TMEM175, INPP5F, SCARB2. Expression analyses highlight SNCA-AS1 potentially SCARB2 differential expression in different brain regions with...

Introduction Parkinson’s disease (PD) is the second most common neurodegenerative disorder, increasing both in terms of prevalence and incidence. To date, only symptomatic treatment available, highlighting need to increase knowledge on etiology order develop new therapeutic strategies. Hemizygosity for gene Engrailed-1 ( En1 ), encoding a conserved transcription factor essential programming, survival, maintenance midbrain dopaminergic neurons, leads progressive nigrostriatal degeneration,...

Open science and collaboration are necessary to facilitate the advancement of Parkinson's disease (PD) research. Hackathons collaborative events that bring together people with different skill sets backgrounds generate resources creative solutions problems. These can be used as training networking opportunities, thus we coordinated a virtual 3-day hackathon event, during which 49 early-career scientists from 12 countries built tools pipelines focus on PD. Resources were created goal helping...

To determine the frequency of mutations known to cause autosomal dominant Parkinson disease (PD) in a series with more than 10% Sweden's estimated number PD patients.The Swedish Disease Genetics Network was formed as national multicenter consortium clinical researchers who together have access DNA from total 2,206 patients; 85.4% were population-based studies. Samples analyzed centrally for pathogenic SNCA (duplications/triplications, p.Ala30Pro, p.Ala53Thr) and LRRK2 (p.Asn1437His,...

Risk factors for Parkinson's disease (PD) can be more or less relevant to a population due population-specific genetic architecture, local lifestyle habits, and environmental exposures. Therefore, it is essential study PD at local, regional, continental scale in order increase the knowledge on etiology.We aimed investigate contribution of new Swedish case-control cohort.PD patients (n = 929) matched population-based controls 935) from southernmost county Sweden were included cohort....

Copy Number Variations (CNVs) play pivotal roles in the etiology of complex diseases and are variable across diverse populations. Understanding association between CNVs disease susceptibility is significant importance genetics research often requires analysis large sample sizes. One most cost-effective scalable methods for detecting based on normalized signal intensity values, such as Log R Ratio (LRR) B Allele Frequency (BAF), from Illumina genotyping arrays. In this study, we present...

Parkinson's disease (PD) is a common, progressive neurodegenerative disease, which typically presents itself with range of motor symptoms, like resting tremor, bradykinesia, and rigidity, but also non-motor symptoms such as fatigue, constipation, sleep disturbance. Neuropathologically, PD characterized by loss dopaminergic cells in the substantia nigra pars compacta (SNpc) Lewy bodies, neuronal inclusions containing α-synuclein (α-syn). Mutations copy number variations SNCA, gene encoding...

Abstract Parkinson’s disease (PD) is a neurodegenerative with an often complex genetic component identifiable by genome-wide association studies (GWAS). The most recent large scale PD GWASes have identified more than 90 independent risk variants for and progression across 80 loci. One major challenge in current genomics identifying the causal gene(s) variant(s) from each GWAS locus.

Parkinson's disease (PD) is a complex neurodegenerative disorder in which both rare and common genetic variants contribute to risk. Multiple genes have been reported be linked monogenic PD but these only explain fraction of the observed familial aggregation. Rare RIC3 suggested associated with Indian population. However, replication studies yielded inconsistent results. We further investigate role European cohorts using individual-level genotyping data from 14,671 patients 17,667 controls,...
