Mutations in TMEM230 were identified as a genetic factor for Parkinson's disease (PD) with typical clinical symptoms and Lewy bodies in a North American population, and a highly prevalent TMEM230 mutation, c.550_552delTAGinsCCCGGG (p.*184ProGlyext*5), was found in 7 Chinese families. In the present study, we investigated the prevalence of TMEM230 mutations(More)
OBJECTIVE To undertake an updated genetic spectrum analysis in patients with hereditary spinocerebellar ataxia (SCA) in mainland China. METHODS SCA 1, 2, 3, 6, 7, 8, 10, 12, 17 and dentatorubral-pallidoluysian atrophy (DRPLA) nucleotide repeat mutations were detected in 430 families with autosomal dominant SCA (ADCA) and 237 patients with sporadic ataxias(More)
BACKGROUND The Short Musculoskeletal Function Assessment (SMFA) questionnaire is one of the most commonly used scales to evaluate functional status and quality of life (QOL) of patients with a broad range of musculoskeletal disorders. However, a Chinese version of the SMFA questionnaire for the psychometric properties of skeletal muscle injury patients in(More)
Orthostatic hypotension (OH) is common in multiple system atrophy (MSA) and Parkinson disease (PD), generally assessed through a lying-to-standing orthostatic test. However, standing blood pressure may not be available due to orthostatic intolerance or immobilization for such patients. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were(More)
The spinocerebellar ataxias (SCAs) are a clinically and genetically heterogeneous group of neurodegenerative diseases. Researchers have recently found that SCA type 11 (SCA11) is associated with mutations in the TTBK2 gene. In our previous work, we performed mutation detection in SCA1, 2, 3, 6, 7, 8, 10, 12, 17 and dentatorubral-pallidoluysian atrophy gene(More)
OBJECTIVE To determine the neuronal damage or loss and gliosis at the cellular level in spinocerebellar ataxia type 3/Machado-Joseph disease(SCA3/MJD), and evaluate the potential use of neuron-specific enolase (NSE) and protein S 100 B(S100B) serum concentrations as biochemical markers. METHODS Serum concentrations of NSE and S100B were measured in 102(More)
OBJECTIVE To evaluate the metabolite pattern and the severity in patients with spinocerebellar ataxia type 3/ Machado-Joseph disease (SCA3/MJD) by (1)H magnetic resonance spectroscopy ((1)H-MRS) on different cerebellar regions, including cerebellar vermis, cerebellar peduncles, cerebellar cortex, and dentatum. METHODS Thirty-six SCA3/MJD patients, and 27(More)
OBJECTIVE To investigate the related factors of international cooperative ataxia rating scale (ICARS) and scale for the assessment and rating of ataxia scores (SARA) in patients with spinocerebellar ataxia type 3/Machado-Joseph disease. METHODS A total of 126 SCA3/MJD patients were assessed by ICARS and SARA. The relation between ICARS or SARA scores and(More)
OBJECTIVE To investigate the CAG trinucleotide repeat expansion in spinocerebellar ataxia (SCA) types 1, 2, 3, 6, 7, 12, and 17 from Chinese Han. METHODS The pathological CAG triplet repeat expansions of the SCA1, SCA2, SCA3/Machado-Joseph disease (MJD), SCA6, SCA7, SCA12 and SCA17 genes were analyzed in a cohort of 559 Mainland Chinese patients affected(More)
