Autosomal recessive cerebellar ataxias are a group of neurodegenerative disorders that are characterized by complex clinical and genetic heterogeneity. Although more than 20 disease-causing genes have been identified, many patients are still currently without a molecular diagnosis. In a two-generation autosomal recessive cerebellar ataxia family, we mapped(More)
BACKGROUND Hereditary spastic paraplegia type 6 (SPG6) is caused by mutations in the NIPA1 gene, this is a rare cause of HSP, until now, all the affected individuals reported displayed "pure" spastic paraplegia. OBJECTIVES To analyze the genotype/phenotype correlation of mutations so far described in NIPA1. METHODS Eighty-six Chinese Han HSP patients(More)
It has been reported that some single-nucleotide polymorphisms (SNPs) are associated with the risk of Parkinson's disease (PD), but whether a combination of these SNPs would have a stronger association with PD than any individual SNP is unknown. Sixteen SNPs located in the 8 genes and/or loci (SNCA, LRRK2, MAPT, GBA, HLA-DR, BST1, PARK16, and PARK17) were(More)
Parkinson's disease (PD) is the second most common neurodegenerative disorder. The presence of Lewy bodies is a major pathological change of PD. α-synuclein is the main component of Lewy bodies and is encoded by the SNCA gene. Mutations in the SNCA gene mainly result in rare familial forms of PD, while genetic variability in the SNCA gene modulates(More)
The Grb10-interacting GYF protein-2 gene (GIGYF2) is a PARK11 gene that reportedly has a causal role in familial Parkinson’s disease (PD) among populations from Italy and France. However, no comprehensive study of the GIGYF2 gene has been conducted among PD patients from mainland China. In our previous study, the GIGYF2 gene was directly sequenced, and nine(More)
Exposure to excessive manganese (Mn) causes manganism, a progressive neurodegenerative disorder similar to idiopathic Parkinson's disease (IPD). The detailed mechanisms of Mn neurotoxicity in nerve cells, especially in dopaminergic neurons are not yet fully understood. Meanwhile, it is unknown whether there exists a potential antagonist or effective drug(More)
Rasagiline, a novel monoamine oxidase (MAO)-B inhibitor, has a mild to moderate effect in relieving Parkinson's disease (PD) symptoms as well as unique neuroprotective effects. Previous studies demonstrated rasagiline protect neurons by regulating Bcl-2 family proteins. Our study aimed to study whether Bcl-2-associated athanogene (BAG)-family proteins,(More)
