Özet:

 

Background/aim: Alzheimer disease (AD) is characterized by the accumulation of senile plaques composed of amyloid β-peptide, which is derived from β-amyloid precursor protein through degradation by β-secretase and γ-secretase complexes. One of the major components of γ-secretase complex, anterior pharynx-defective-1 (APH-1), is responsible for the activity of the γ-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.   Materials and methods: In this study, 49 AD patients and 45 healthy controls were included. The genetic polymorphisms and allele frequencies of APOE and APH-1a were investigated. Patients were evaluated for behavioral, cognitive, and functional domains by detailed neurocognitive tests, and comparison between the above-mentioned polymorphisms and disease severity was made.   Results: Although there was an increased tendency of the APO ?4 allele in the AD group, no statistically significant difference was detected either in APOE or APH-1a polymorphisms, not suggesting a strong susceptibility to the development of AD.  Conclusion: While searching for the pathogenesis of AD in order to develop novel diagnostic as well as therapeutic approaches, analysis of other genes with a possible role in AD is warranted.
