Association of a BACE1 Gene Polymorphism with Parkinson's Disease in a Norwegian Population.

ABSTRACT: Background. Parkinson's disease (PD) and Alzheimer's disease (AD) share pathological features, including amyloid-beta pathology. Amyloid-beta peptide is generated by sequential proteolysis of amyloid precursor protein (APP), and genetic variations in the processing pathway genes have been found to increase the risk of AD; however, the contribution in PD is unknown. Methods. The aim of this study was to investigate whether candidate polymorphisms in five genes (ADAM10, BACE1, BACE2, PSEN2, and CLU) involved in the APP processing pathway affect PD risk in a population-based cohort of patients with incident PD and control subjects from the Norwegian ParkWest study. Results. We found an association of rs638405 in BACE1 with increased risk of PD, thus providing a novel link, at the genetic level, between amyloid-beta pathology and PD.

Association of ATG5 gene polymorphism with Parkinson's disease in a Han Chinese population.

Project description:PurposeThere is growing evidence that autophagy-related gene 5 (ATG5) is involved in neural development, neuronal differentiation, and neurodegenerative diseases. The purpose of this study was to investigate the association between ATG5 gene single-nucleotide polymorphisms (SNPs) and Parkinson's disease (PD) in the Han population.MethodsA case-control study was conducted in 120 PD patients and 100 healthy volunteers. MassArray platform was used to analyze polymorphisms in three different regions of ATG5 gene (rs510432, rs573775 and rs17587319). In the included subjects, 50 PD patients and 50 healthy volunteers were selected, and the plasma ATG5 concentration was detected by enzyme-linked immunosorbent assay (ELISA). The allele and genotype frequencies of SNPs were assessed using the SHEsis program.ResultsWe found a significant correlation between rs17587319 and PD, and the subcomponent showed a high correlation between rs17587319 with cognitive impairment and age at onset in PD patients. At the same time, the total plasma ATG5 level of PD patients and the plasma ATG5 expression level of early-onset Parkinson's disease (EOPD) patients were significantly higher than the control group, while there was no significant difference of ATG5 expression between late-onset Parkinson's disease (LOPD) patients and the control group.ConclusionThese findings suggest that genetic variations in the ATG5 gene and low levels of the ATG5 protein are associated with susceptibility to PD and with cognitive impairment in PD patients. ATG5 could be a potential biomarker to assess the severity and prognosis of PD.

Association between GRN rs5848 polymorphism and Parkinson's disease in Taiwanese population.

Project description:A single nucleotide polymorphism GRN rs5848 (3'UTR+78 C>T) was reported to alter the risk for frontotemporal lobar degeneration. Herein, we investigated the effect of GRN rs5848 on the risk of Parkinson's disease (PD) by genotyping 573 Taiwanese patients with PD and 490 age-matched control subjects. Compared to subjects with CC genotype, those with TT genotype had a 1.58-fold increased risk of PD (95% CI: 1.77∼2.34, P = 0.021). PD patients demonstrate a higher frequency of T allele (37.2%) than controls (32.2%; odds ratio [OR] = 1.24, 95% CI: 1.04∼1.49, P = 0.017). This susceptibility was particularly observed in female subjects, in which TT genotype had a 2.16-fold increased risk of PD as compared with controls(95% CI: 1.24∼3.78, P = 0.006). The frequency of T allele (39.3%) in female PD patients was higher than in female control subjects (31.1%; OR = 1.43, CI: 1.11∼1.87, P = 0.007). No association was observed between GRN rs5848 and susceptibility in male subjects. These findings show that the GRN rs5848 TT genotype and T allele are risk factors for female Taiwanese patients with PD.

Association study of TREM2 polymorphism rs75932628 with leucoaraiosis or Parkinson's disease in the Han Chinese population.

Project description:ObjectivesThe previously reported functional mutation rs75932628-T (p.R47H) in the triggering receptor expressed on myeloid cells 2 (TREM2) is a genetic risk factor for Alzheimer's disease, Parkinson's disease (PD) and frontotemporal dementia, in European populations. This study aims to assess the genetic association of the variant rs75932628-T with PD and leucoaraiosis (LA) in a Han Chinese population.SettingThis population-based study was conducted in China by Xiamen University and its affiliated hospital.Participants308 patients with LA, 342 patients with PD and 198 healthy blood donors were recruited from the First Affiliated Hospital of Xiamen University.Outcome measuresGenotyping was performed by molecular beacon real-time PCR and Sanger sequencing.ResultsNone of our participants carried the rs75932628-T mutation.ConclusionsOur results corroborate and extend previous findings, concluding that the variant rs75932628-T (p.R47H) in TREM2 is not a risk factor for LA or PD in the Han Chinese population.

Possible association of CCDC62 rs12817488 polymorphism and Parkinson's disease risk in Chinese population: a meta-analysis.

Project description:Conflicting results identifying the association between coiled-coil domain containing 62 (CCDC62) polymorphism, rs12817488, and Parkinson's disease (PD) have been reported. To clarify whether rs12817488 is related to PD risk in Chinese population, we carried out this meta-analysis by searching literature from PubMed and Embase database regarding this polymorphism. Three eligible studies involving 1616 cases and 1649 controls were included in this meta-analysis. Our results showed statistically significant association between rs12817488 and PD risk in all four genetic models. Stratification by gender revealed similar results in both subgroup in these genetic models except for recessive model, in which rs12817488 was not significantly associated with PD in male subgroup. Unstable result was found in recessive model via sensitivity analysis, and publication bias was observed in recessive model as well, indicating that the pooled result from recessive model should be cautiously treated. Our meta-analysis implicates a possible relationship between rs12817488 and PD risk in Chinese population. Further validation of this association in large sample size study with different gender is warranted.

Fibroblast Growth Factor 20 Gene Polymorphism in Parkinson's Disease in Asian Population: A Meta-Analysis.

Project description:Parkinson's disease (PD) is a neurodegenerative disease with the pathological hallmark of Lewy bodies and Lewy neurites composed of α-synuclein. The SNP rs591323 is one of the risk loci located near the FGF20 gene that has been implicated in PD. The variation of FGF20 in the 3' untranslated region was shown to increase α-synuclein expression. We examined the association of rs591323 with the risk of PD in a Taiwanese population and conducted a meta-analysis, including our study and two other studies from China, to further confirm the role of this SNP in Taiwanese/Chinese populations. A total of 586 patients with PD and 586 health controls (HCs) were included in our study. We found that the minor allele (A) and the AA + GA genotype under the dominant model are significantly less frequent in PD than in controls. The meta-analysis consisted of 1950 patients with PD and 2073 healthy controls from three studies. There was significant association between rs591323 and the risk of PD in the additive (Z = -3.96; p < 0.0001) and the dominant models (Z = -4.01; p < 0.0001). Our study results and the meta-analysis support the possible protective role of the rs591323 A allele in PD in Taiwanese/Chinese populations.

Association of BACE1 Gene Polymorphism with Cerebellar Volume but Not Cognitive Function in Normal Individuals.

Project description:AIMS:?-Site amyloid precursor protein (APP)-cleaving enzyme 1 (BACE1) is a biological and positional candidate gene for Alzheimer's disease (AD). Previous studies found that BACE1-null mice had impaired performance on cognition and neurodegeneration during the aging process. Additionally, a synonymous polymorphism of BACE1 (rs638405) in exon 5 has been reported to be associated with risk for AD. We hypothesized that this BACE1 gene variant might influence regional brain volumes and cognitive tests in normal individuals. METHODS:Participants were 330 normal volunteers between 21 and 92 years of age (mean age 56.3 ± 22.0 years; 191 males, 139 females). Cognitive tests (the Mini-Mental State Examination and Digit Spans), magnetic resonance imaging, and genotyping of BACE1 rs638405 were examined for each subject. The differences in regional gray matter (GM) volumes between G homozygotes and C-allele carriers were tested using optimized voxel-based morphometry. RESULTS:Compared to C-allele carriers, G homozygotes exhibited significantly larger GM volumes in the left cerebellar culmen and right cerebellar lingual area, but no significant differences on cognitive function tests. CONCLUSION:The findings suggest that the BACE1 rs638405 polymorphism may affect cerebellar morphology, but not cognitive function in healthy humans.

Lack of Association Between DJ-1 Gene Promoter Polymorphism and the Risk of Parkinson's Disease.

Project description:Low DJ-1 protein level caused by DJ-1 gene mutation leads to autosomal recessive Parkinson's disease (PD) due to impaired antioxidative activity. In sporadic PD patients, although mutations were rarely found, lower DJ-1 protein level was also reported. Dysregulation of DJ-1 gene expression might contribute to low DJ-1 protein level. Since the promoter is the most important element to initiate gene expression, whether polymorphisms in the DJ-1 promoter result in the dysregulation of gene expression, thus leading to low protein level and causing PD, is worth exploring. The DJ-1 promoter region was sequenced in a Chinese cohort to evaluate possible links between DJ-1 promoter polymorphisms, PD risk and clinical phenotypes. Dual-luciferase reporter assay was conducted to evaluate the influence of promoter polymorphisms on DJ-1 transcriptional activity. Related information in an existing genome-wide association studies (GWAS) database were looked up, meta-analysis of the present study and other previous reports was conducted, and expression quantitative trait loci (eQTL) analysis was performed to further explore the association. Three single nucleotide polymorphisms (SNPs) (rs17523802, rs226249, and rs35675666) and one 18 bp deletion (rs200968609) were observed in our cohort. However, there was no significant association between the four detected genetic variations and the risk of PD either in allelic or genotype model, in single-point analysis or haplotype analysis. This was supported by the meta-analysis of this study and previous reports as well as that of GWAS database PDGene. Dual luciferase reporter assay suggested these promoter polymorphisms had no influence on DJ-1 transcriptive activity, which is consistent with the eQTL analysis results using the data from GTEx database. Thus, DJ-1 promoter polymorphisms may play little role in the dysregulation of DJ-1 expression and PD susceptibility in sporadic PD.

Association between BACE1 gene polymorphisms and focal seizures in a Chinese Han population.

Project description:Beta-secretase 1 (BACE1) is attracting increasing attention for its vital role in pathogenesis of many neuropsychiatric disorders and many studies also have indicated BACE1 as a possible risk factor for seizures, but not any studies have reported association between BACE1 gene polymorphisms and seizures. Therefore, we investigated the possible association between focal seizures and BACE1 gene polymorphisms in the present study.A total of 162 patients and 211 health controls were enrolled in this study and polymorphisms of BACE1 gene were detected using polymerase chain reaction (PCR)-ligase detection reaction method.The frequency of genotype AT for BACE1 rs535860 (A>T) was significantly higher (24.1%) in patients compared to controls (14.7%) (OR?=?1.836, 95% CI?=?1.086-3.102, P?=?.023). Intriguingly, we only found the significant difference of BACE1 SNP genotype and allele frequency among males but not females. However, no statistically significant results were presented for the genotype distributions of rs525493 (G>T) and rs638405(C>G) polymorphisms between patients and controls.Our study demonstrated there may exist an association between BACE1 rs535860 (A>T) polymorphism and focal seizures in Chinese Han males.

Association of CALHM1 Gene Polymorphism with Late Onset Alzheimer's Disease in Iranian Population.

Project description:Alzheimer's disease (AD) is a genetically heterogeneous neurodegenerative disease and Late-Onset type (LOAD) is the most common form of dementia affecting people over 65 years old. CALHM1 (P86L) encodes a transmembrane glycoprotein that controls cytosolic Ca(2+) concentrations and A? levels and P86L polymorphism in this gene is significantly associated with LOAD in independent case controls in a number of studies. This study was performed to determine whether this polymorphism contributes to the risk for LOAD in Iranian population. One hundred and forty one AD patients and 141 healthy controls were recruited in this study. After extraction of genomic DNA, the genotype and allele frequencies were determined in case and control subjects using PCR/RFLP method. The statistical analysis showed a significant difference in the heterozygote genotype frequency in case and control groups and polymorphic allele had a protective role between two groups. Also after stratifying the subjects by their APOE-?4 status, no significant association was observed. Our study suggests that P86L polymorphism could be a protective factor for late-onset Alzheimer's disease (LOAD) in Iranian population. However, to confirm these results, further study with a bigger sample size may be required.

The UCHL1 S18Y polymorphism and Parkinson's disease in a Japanese population.

Project description:UCHL1 plays an important role in the ubiquitin-proteasome system and is a biologically plausible candidate gene for Parkinson's disease (PD). However, results from genetic association studies of the UCHL1 S18Y polymorphism have been equivocal. Meta-analyses indicate that the polymorphism's risk effect might be restricted to Asian populations and early-onset disease. To further explore the role of UCHL1 in PD, we genotyped S18Y in 605 PD patients and 1620 controls of Japanese ancestry. We did not find evidence of an association in the overall sample (SY vs. SS: adjusted OR=1.11, P=0.37; YY vs. SS: adjusted OR=1.01, P=0.94). In the early-onset stratum, however, we observed a trend toward a reduction in risk for those with the Y allele (SY vs. SS, adjusted OR, 0.75; 95% CI, 0.47-1.20; YY vs. SS, OR, 0.64; 95% CI, 0.36-1.14; trend test, P=0.12). These results indicate that, if involved in PD, the S18Y variant is not a major determinant of risk and its effect might be restricted to early-onset disease.
