The þ1073 C/T polymorphism of the oxidized low-density lipoprotein receptor-1 (OLR1) gene has been reported to be associated with late-onset Alzheimer’s disease, whereas for the þ1071 T/A polymorphism no association was found. We genotyped 169 sporadic Alzheimer’s disease patients and 264 sex- and age-matched nondemented controls from Southern Italy for OLR1 þ1073 C/T and þ1071 T/A polymorphisms and for apolipoprotein E and LBP-1c/CP2/LSF.

Abstract

The þ1073 C/T polymorphism of the oxidized low-density lipoprotein receptor-1 (OLR1) gene has been reported to be associated with late-onset Alzheimer’s disease, whereas for the þ1071 T/A polymorphism no association was found. We genotyped 169 sporadic Alzheimer’s disease patients and 264 sex- and age-matched nondemented controls from Southern Italy for OLR1 þ1073 C/T and þ1071 T/A polymorphisms and for apolipoprotein E and LBP-1c/CP2/LSF. We also performed haplotype analysis. For the þ1073 C/T polymorphism, the C allele and the CC genotype have been associated with a higher risk for Alzheimer’s disease without apolipoprotein E or CP2 interaction. The two polymorphisms were in linkage disequilibrium, with the haplotype T-C at significant increased risk of developing Alzheimer’s disease in the whole sample and in elderly persons 70 years or older. In our population, the þ1073 C/T OLR1 polymorphism exhibited a significant association with Alzheimer’s disease, further supporting the role of OLR1 as a candidate risk gene for sporadic Alzheimer’s disease
