Determination of Deleterious SNPs in APH1A Gene Related to Alzheimers Disease by In Silico Methods
Alzheimers disease (AD) is a progressive neurodegenerative disease characterized by pathological accumulation of ?-amyloid (A?) senile plaques and neurofibrillary tangles. ?-secretase produces the amyloid ? peptide (A?), which causes AD. ?-secretase is a macromolecular complex and the protein encode...

Alzheimers disease (AD) is a progressive neurodegenerative disease characterized by pathological accumulation of ?-amyloid (A?) senile plaques and neurofibrillary tangles. ?-secretase produces the amyloid ? peptide (A?), which causes AD. ?-secretase is a macromolecular complex and the protein encoded by the APH1A gene is located in this complex. In this study, it was aimed to determine the possible deleterious effects of missense single nucleotide polymorphisms (SNPs) in APH1A gene on the protein structure and stabilization via in silico methods. PolyPhen-2 and SIFT were used to predict deleterious SNPs, I-Mutant 2.0 software was used to detect protein stabilization changes and Project HOPE software tool was used to make three-dimensional modeling of wild and mutant type proteins. The results showed that 257 SNPs among a total of 3567 SNPs in the APH1A gene were missense SNPs. According to the in silico analysis of the 257 SNPs it has been determined that rs11548266, rs74126634, rs145324799, rs199961673, rs370361277, rs370719475 and rs376071112 polymorphisms may have deleterious effects.
