Genetic assessment of familial and early-onset Parkinson's disease in a Greek population
(2014)
Background and purpose Although the first mutation associated with Parkinson's disease (PD) was identified several years ago in the alpha-synuclein (SNCA) gene in families of Greek and Italian ancestry, a more systematic ...
The interplay between environmental and genetic factors in Parkinson's disease susceptibility: The evidence for pesticides
(2013)
Parkinson's disease (PD) is a common neurodegenerative disorder characterized by dopaminergic neuron loss in the substantia nigra. Several genetic and environmental factors have been implicated in the pathogenesis of PD. ...
The protective effect of LRRK2 p.R1398H on risk of Parkinson's disease is independent of MAPT and SNCA variants
(2014)
The best validated susceptibility variants for Parkinson's disease are located in the α-synuclein (SNCA) and microtubule-associated protein tau (MAPT) genes. Recently, a protective p.N551K-R1398H-K1423K haplotype in the ...
Population-specific Frequencies for LRRK2 Susceptibility Variants in the Genetic Epidemiology of Parkinson's Disease (GEO-PD) Consortium
(2013)
BackgroundVariants within the leucine-rich repeat kinase 2 gene are recognized as the most frequent genetic cause of Parkinson's disease. Leucine-rich repeat kinase 2 variation related to disease susceptibility displays ...
Non-replication of association for six polymorphisms from meta-analysis of genome-wide association studies of Parkinson's disease: Large-scale collaborative study
(2010)
Early genome-wide association (GWA) studies on Parkinson's disease (PD) have not been able to yield conclusive, replicable signals of association, perhaps due to limited sample size. We aimed to investigate whether association ...
Assessment of Parkinson's disease risk loci in Greece
(2014)
Genome-wide association studies (GWAS) have been shown to be a powerful approach to identify risk loci for neurodegenerative diseases. Recent GWAS in Parkinson's disease (PD) have been successful in identifying numerous ...
Association of tau haplotype-tagging polymorphisms with Parkinson's disease in diverse ethnic Parkinson's disease cohorts
(2006)
Background: The overlap in the clinical and pathological features of tauopathies and synucleinopathies raises the possibility that the tau protein may be important in Parkinson's disease (PD) pathogenesis. Several MAPT ...
A large-scale genetic association study to evaluate the contribution of Omi/HtrA2 (PARK13) to Parkinson's disease
(2011)
High-profile studies have provided conflicting results regarding the involvement of the Omi/HtrA2 gene in Parkinson's disease (PD) susceptibility. Therefore, we performed a large-scale analysis of the association of common ...
The human prion gene M129V polymorphism is not associated with idiopathic Parkinson's disease in three distinct populations
(2006)
Coexistence of prion disease and idiopathic Parkinson's disease (TPD) has been previously described. It remains unclear whether this relationship may reflect the high incidence of IPD or whether both prion and IPD share ...
