Background/aim: Alzheimer disease (AD) is characterized by the accumulation of senile plaques composed of amyloid beta-peptide, which is derived from beta-amyloid precursor protein through degradation by beta-secretase and.-secretase complexes. One of the major components of gamma-secretase complex, anterior pharynx-defective-1 (APH-1), is responsible for the activity of the.-secretase complex. In this study, we searched for not only the most known common genetic risk factor, APOE, but also the APH-1a gene polymorphism in AD patients in a Turkish population.
