Genomic triplication of the alpha-synuclein gene (SNCA) has been reported to cause hereditary early-onset parkinsonism with dementia. These findings prompted us to screen for multiplication of the SNCA locus in nine families in whom parkinsonism segregates as an autosomal dominant trait. One kindred was identified with SNCA duplication by semiquantitative(More)
Genome-wide analysis of a multi-incident family with autosomal-dominant parkinsonism has implicated a locus on chromosomal region 3q26-q28. Linkage and disease segregation is explained by a missense mutation c.3614G>A (p.Arg1205His) in eukaryotic translation initiation factor 4-gamma (EIF4G1). Subsequent sequence and genotype analysis identified EIF4G1(More)
To gain insight into systemic molecular events associated with an age-related neurodegenerative disorder, we compared gene expression patterns in peripheral blood mononuclear cells (PBMCs) sampled from elderly, healthy controls and from Parkinson's disease (PD) patients carrying the most frequently found mutation of the LRRK2 gene (G2019S). A transcriptomic(More)
Genomic multiplication of the alpha-synuclein gene (SNCA) locus is one cause of familial Parkinson disease (PD). We performed detailed genomic, SNCA expression level, clinical, neuropsychological and functional imaging analyses of a parkinsonian kindred with a known duplication of the SNCA locus. We demonstrated that the duplication spanned 4.928 Mb(More)
OBJECTIVE Copy number variation is a common polymorphic phenomenon within the human genome. Although the majority of these events are non-deleterious they can also be highly pathogenic. Herein we characterize five families with parkinsonism that have been identified to harbor multiplication of the chromosomal 4q21 locus containing the alpha-synuclein gene(More)
