A total sample of 169 AD patients, and 264 age- and sex-matched unrelated caregivers from Apulia, southern Italy, were genotypized for alpha-2-macroglobulin (A2M) Val1000/Ile single-nucleotide polymorphism (SNP) (rs669), apolipoprotein E (APOE), and SNPs (+1073 and +1071) in the oxidized low-density lipoprotein receptor-1 (OLR1) gene on chromosome 12. A2M allele and genotype frequencies were similar between AD patients and controls, also after stratification for late onset (>/=70 years) and early onset (<70 years) or APOE varepsilon4 status. However, there was evidence in support of LD between the OLR1+1071, the OLR1+1073, and the rs669 SNPs, with T-C-A haplotype being associated with significant increased risk of AD in both the whole sample and when we stratified according to early and late onset AD subjects, with the allelic association with AD predominantly from the OLR1+1073 SNP, further supporting the role of OLR1 as a candidate risk gene for sporadic AD.

THIS RESOURCE IS NO LONGER IN SERVICE. Documented on January 4, 2023. Database that provides special browsing capabilities for a subset of organisms in Entrez Genomes. Map Viewer allows users to view and search an organism's complete genome, display chromosome maps, and zoom into progressively greater levels of detail, down to the sequence data for a region of interest. If multiple maps are available for a chromosome, it displays them aligned to each other based on shared marker and gene names, and, for the sequence maps, based on a common sequence coordinate system.
