    • A functional intracellular transport system is essential to maintain cell shape and function especially in elongated cells, e.g. neurons and lens fibre cells. Impaired intracellular transport has been suggested as a common pathological mechanism for age-related diseases characterised by protein aggregation. Here, we hypothesise that common genetic variation in the transport protein kinesin may influence the risk of Parkinson's disease (PD), Alzheimer's disease (AD) and age-related cataract. This case-control study involves a PD material (165 cases and 190 controls), an AD material (653 cases and 845 controls) and a cataract material (495 cases and 183 controls). Genetic variation in the kinesin light chain 1-encoding gene (KLC1) was tagged by six tag single nucleotide polymorphisms (SNPs). Single SNPs and haplotypes were analysed for associations with disease risk, age parameters, mini-mental state examination scores and cerebrospinal fluid biomarkers for AD using logistic or linear regression. Genetic variation in KLC1 did not influence risk of PD. Weak associations with risk of AD were seen for rs8007903 and rs3212079 (P (c) = 0.04 and P (c) = 0.02, respectively). Two SNPs (rs8007903 and rs8702) influenced risk of cataract (P (c) = 0.0007 and P (c) = 0.04, respectively). However, the allele of rs8007903 that caused increased risk of AD caused reduced risk of cataract, speaking against a common functional effect of this particular SNP in the two diseases. Haplotype analyses did not add significantly to the associations found in the single SNP analyses. Altogether, these results do not convincingly support KLC1 as a major susceptibility gene in any of the studied diseases, although there is a small effect of KLC1 in relation to cataract.

  • Nrf2-encoding NFE2L2 haplotypes influence disease progression but not risk in Alzheimer's disease and age-related cataract.

    • Alzheimer's disease (AD) and age-related cataract, disorders characterized by protein aggregation causing late-onset disease, both involve oxidative stress. We hypothesize that common variants of NFE2L2 and KEAP1, the genes encoding the main regulators of the Nrf2 system, an important defence system against oxidative stress, may influence risk of AD and/or age-related cataract. This case-control study combines an AD material (725 cases and 845 controls), and a cataract material (489 cases and 182 controls). Genetic variation in NFE2L2 and KEAP1 was tagged by eight and three tag single nucleotide polymorphisms (SNPs), respectively. Single SNPs and haplotypes were analyzed for associations with disease risk, age parameters, MMSE and AD cerebrospinal fluid biomarkers. NFE2L2 and KEAP1 were not associated with risk of AD or cataract. However, one haplotype allele of NFE2L2 was associated with 2 years earlier age at AD onset (pc 0.013) and 4 years earlier age at surgery for posterior subcapsular cataract (p(c) = 0.019). Another haplotype of NFE2L2 was associated with 4 years later age at surgery for cortical cataract (p(c) = 0.009). Our findings do not support NFE2L2 or KEAP1 as susceptibility genes for AD or cataract. However, common variants of the NFE2L2 gene may affect disease progression, potentially altering clinically recognized disease onset. (C) 2010 Elsevier Ireland Ltd. All rights reserved.
