title: Case-control study and meta-analysis of low density lipoprotein receptor-related protein gene exon 3 polymorphism in Alzheimer's disease.
abstract: The low density lipoprotein receptor-related protein (LRP) may influence both the clearance and the production of beta-amyloid peptide and thus plays a role in Alzheimer's disease (AD) pathogenesis. Previous studies, although inconsistent, have suggested that the LRP exon 3 CC genotype contributes to the risk of AD. A case-control study utilizing a clinically well-defined group of 305 sporadic AD patients and 304 control subjects was performed to test this association in an ethnically homogeneous population from Spain. In the current study, the LRP CC genotype was not over-represented in AD patients compared to non-demented controls. A meta-analysis of previous studies revealed a weak correlation of LRP CC genotype with AD (odds ratio of 1.35, P=0.01).
