To identify rare causal variants in late-onset Parkinson disease (PD), we investigated an Austrian family with 16 affected individuals by exome sequencing. We found a missense mutation, c.1858G>A (p.Asp620Asn), in the VPS35 gene in all seven affected family members who are alive. By screening additional PD cases, we saw the same variant cosegregating with(More)
We identified a marker in LINGO1 showing genome-wide significant association (P = 1.2 x 10(-9), odds ratio = 1.55) with essential tremor. LINGO1 has potent, negative regulatory influences on neuronal survival and is also important in regulating both central-nervous-system axon regeneration and oligodendrocyte maturation. Increased axon integrity observed in(More)
Mutations in the valosin-containing protein (VCP) are known to cause autosomal-dominant inclusion-body myopathy with Paget's disease of bone and frontotemporal dementia (IBMPFD). We report a novel missense mutation (G157R) in the N-terminal region of the VCP gene in a German family. Family members presented with mild to moderate proximal muscle weakness,(More)
Mutations in the valosin-containing protein (VCP) on chromosome 9p13-p12 were recently found to be associated with hereditary inclusion body myopathy, Paget disease of the bone, and frontotemporal dementia (IBMPFD). We identified a novel missense mutation in the VCP gene (R159H; 688G>A) segregating with this disease in an Austrian family of four affected(More)
BACKGROUND Genetic variation in the glucocerebrosidase (GBA) gene is strongly associated with Parkinson's disease (PD). Transport of glucocerebrosidase to the lysosome involves the protein encoded by the SCARB2 gene. An association between the common SNP rs6812193, upstream of SCARB2, and PD has been reported previously. The role of exonic variants in the(More)
BACKGROUND Antonovsky's salutogenic model of the "Sense of Coherence" (SOC) is an important resource in dealing with chronic diseases. The aim of this study was to investigate SOC as a psychological factor and its correlation with illness, subjective well-being, and health-related quality of life (QoL) in patients with Parkinson disease (PD) compared to(More)
BACKGROUND Families associated with missense mutations in the valosin-containing protein (VCP) present with a rare autosomal dominant multisystem disorder of frontotemporal lobar degeneration (FTLD), inclusion body myopathy (IBM), and Paget disease of bone (PDB), referred to as IBMPFD. METHODS We used exon-based genomic DNA sequencing to test for VCP(More)
The GIGYF2 (Grb10-Interacting GYF Protein-2) gene has recently been proposed to be the responsible gene for the PARK11 locus. Ten different putative pathogenic variants were identified in cohorts of Parkinson's disease (PD) patients from Italy and France. Among these variants Asn56Ser and Asn457Thr were found repeatedly. In the present study we screened 669(More)
Mouse units used to quantify the activity of botulinum A toxin preparations are not equivalent and issues concerning efficacy and safety remain with regard to their respective potencies and diffusion qualities in human tissue. We compared the effects of Botox (BOT) and Dysport (DYS) in different doses and dilutions in a human skin model. Eighteen (8 women,(More)
The transcription factors PITX3 and Engrailed 1 (EN1), among others, have been shown to play a crucial role in the maturation and survival of midbrain dopaminergic neurons. The degeneration of those neurons is the pathological hallmark in Parkinson's disease (PD). In a hypothesis-driven candidate gene approach, it has been recently shown that polymorphisms(More)
