A recent collaborative study that combined linkage analysis with whole-genome sequencing of family members of multiplex families with multiple system atrophy (MSA) has identified COQ2 gene as a causative gene for MSA. The common variant, c.T1178C (p.V393A, rs148156462), in the COQ2 gene was found to be associated with an increased risk of sporadic MSA.(More)
A recent study identified a missense mutation in coiled-coil-helix-coiled-coil-helix domain-containing 2 (CHCHD2) gene, p.Thr61Ile, in a Japanese multigenerational family with autosomal dominant Parkinson's disease (PD). Subsequent analyses identified several genetic variants in this gene that contributed to increased risk of sporadic PD, making CHCHD2 a(More)
INTRODUCTION Leucine-rich repeat kinase 2 (LRRK2) mutations are the most common genetic cause of Parkinson's disease (PD). However, only few cases carrying LRRK2 mutations have been reported in Taiwanese PD patients. METHODS We used targeted next generation sequencing (NGS), covering 24 candidate genes involved in neurodegenerative disorders, to analyze(More)
Whole-exome sequencing recently identified a homozygous truncating mutation in Synaptojanin 1 (SYNJ1, PARK20), p.Arg258Gln, in 2 independent families with autosomal recessive young-onset parkinsonism with seizures and cognitive decline. This mutation's role in typical Parkinson's disease (PD) is unclear. We sequenced all coding exons and exon-intron(More)
Mutations in transmembrane protein 230 (TMEM230) have recently been reported to be associated with Parkinson's disease (PD) in a North American population. A highly prevalent mutation, c.550_552delTAGinsCCCGGG (p.*184ProGlyext*5) was found in 3.1% of Chinese familial PD patients. However, subsequent studies failed to replicate these findings in different(More)
