Abstract

Genome scans in sporadic Alzheimer's disease (AD) have revealed possible susceptibility loci on chromosome 12. Recently, two studies were published investigating the +1071 and +1073 polymorphisms in the lectin-like oxidised low density lipoprotein receptor (OLR1) gene with AD, a gene that lies within the area of chromosome 12 linkage. OLR1 is a good candidate gene, due to its function in lipid metabolism pathways, other components of which have been previously implicated as risk factors for AD. We undertook an association study in our UK cohort of 356 AD patients and 358 matched controls, using the same polymorphisms and performing the same sub-group and haplotype analysis as previously described. We found no association with AD in our case-control group as a whole, or when stratified into those with early (<65 years) or late (>65 years) onset. When the group was split into APOE 64 bearers and 64 non-bearers, we could not confirm the associations described in the original study. Similarly, no significant differences were observed between AD patients and controls, in terms of their haplotype distributions. Therefore, in this present study, we find no evidence for the involvement of these ORL1 polymorphisms in increasing susceptibility to AD. (C) 2004 Elsevier Ireland Ltd. All rights reserved.
