DNA tests in normal subjects and patients with ataxia and Parkinson's disease (PD) were carried out to assess the frequency of spinocerebellar ataxia (SCA) and to document the distribution of SCA mutations underlying ethnic Chinese in Taiwan. MJD/SCA3 (46%) was the most common autosomal dominant SCA in the Taiwanese cohort, followed by SCA6 (18%) and SCA1 (3%). No expansions of SCA types 2, 10, 12, or dentatorubropallidoluysian atrophy (DRPLA) were detected. The clinical phenotypes of these affected SCA patients were very heterogeneous. All of them showed clinical symptoms of cerebellar ataxia, with or without other associated features. The frequencies of large normal alleles are closely associated with the prevalence of SCA1, SCA2, MJD/SCA3, SCA6, and DRPLA among Taiwanese, Japanese, and Caucasians. Interestingly, abnormal expansions of SCA8 and SCA17 genes were detected in patients with PD. The clinical presentation for these patients is typical of idiopathic PD with the following characteristics: late onset of disease, resting tremor in the limbs, rigidity, bradykinesia, and a good response to levodopa. This study appears to be the first report describing the PD phenotype in association with an expanded allele in the TATA-binding protein gene and suggests that SCA8 may also be a cause of typical PD.

X-linked dystonia-parkinsonism (XDP, DYT3), endemic in the Philippine island of Panay, is characterized by the clinical onset with dystonia followed by parkinsonism. We found a 35-year-old American male patient, originally from Panay with typical XDP, has a 2-year history of parkinsonism, dystonia, and tremor. Ancestral DYT3 haplotype and disease-specific SVA (short interspersed nuclear element, variable number of tandem repeats, and Alu composite) retrotransposon insertion were identified in the DYT3 proband and two female unaffected family members. No mutation(s) and expression changes in peripheral blood lymphocytes were observed in the TATA-binding protein-associated factor 1 gene (TAF1) or the chemokine CXC motif receptor 3 gene (CXCR3) of the proband or other DYT3 carriers. These findings indicate blood DNA test has a diagnostic utility and implications for genetic counseling in families with DYT3. In contrast, TAF1 and CXCR3 gene expression in peripheral blood lymphocytes is not a suitable surrogate disease marker for DYT3.
