The main objective of this study is to determine the prevalence of apolipoprotein E (Apo E) and glutathione peroxidase 1 (GPX1) polymorphisms and their influence on the development of Alzheimer disease (AD) in the Ecuadorian population. ⋯ Apo E is not a risk factor, nor a protective one for AD, whereas the leu allele of GPX1 is a possible risk factor for the disease.
