Abstract

Background: Oxidative stress and neuronal cell death have been implicated in the pathogenesis of Alzheimer disease (AD). Considering that the glutathiqne transferase (GST) supergene family encodes isoenzymes that appear to be critical in protection against oxidative stress, we aimed at determining the various GSTP1, GSTM1, and GSTT1 polymorphisms and ApoE geno-types to investigate their role as susceptibility genes for late-onset AD (LOAD). Methods: We included 210 LOAD patients and 228 healthy controls matched for age, sex, and educational level in our case-control genetic association study. GSTM1 and GSTT1 genotypes were studied by conventional PCR, whereas GSTP1 and ApoE genotypes were determined by real-time PCR on the LightCycler. Results: We found a significant association between LOAD and the GSTP1*C allelic variant [odds ratio (OR) = 1.9; P
