    • Mitochondrial (mt) dysfunction has been implicated in Alzheimer's (AD) and Parkinson's disease (PD). Mitochondrial transcription factor A (TFAM) is needed for mtDNA maintenance, regulating mtDNA copy number and is absolutely required for transcriptional initiation at mtDNA promoters. Two genetic variants in TFAM have been reported to be associated with AD in a Caucasian case-control material collected from Germany, Switzerland and Italy. One of these variants was reported to show a tendency for association with AD in a pooled Scottish and Swedish case-control material and the other variant was reported to be associated with AD in a recent meta-analysis. We investigated these two genetic variants, rs1937 and rs2306604, in an AD and a PD case-control material, both from Sweden and found significant genotypic as well as allelic association to marker rs2306604 in the AD case-control material (P=0.05 and P=0.03, respectively), where the A-allele appears to increase risk for developing AD. No association was observed for marker rs1937. We did not find any association in the PD case-control material for either of the two markers. The distribution of the two-locus haplotype frequencies (based on rs1937 and rs2306604) did not differ significantly between affected individuals and controls in the two sample sets. However, the global P-value for haplotypic association testing indicated borderline association in the AD sample set. Our data suggests that the rs2306604 A-allele could be a moderate risk factor for AD, which is supported by the recent meta-analysis.

  • S18Y in ubiquitin carboxy-terminal hydrolase L1 (UCH-L1) associated with decreased risk of Parkinson's disease in Sweden.
  • 2007
  • In: Parkinsonism & related disorders. - : Elsevier BV. - 1353-8020. ; 13:5, s. 295-8
  • Journal article (peer-reviewed)abstract
    • Ubiquitin carboxy-terminal hydrolase L1 (UCH-L1) is a neuron-specific enzyme that removes ubiquitin from the C-terminal end of substrates and a component of the ubiquitin-proteasome system. A protective effect of a UCH-L1 variant, S18Y, was suggested since the common variant was found to be inversely associated with sporadic Parkinson's disease (PD). We investigated the association of S18Y in our Swedish PD material. The tyrosine variant was significantly inversely associated with PD (P=0.049) and with a low age of onset (50 years) (P=0.017) in the case-control material, supporting the hypothesis of a protective function.
