عنوان انگلیسی Association of G/C (rs638405) Polymorphism in β-secretase Gene with Alzheimer’s Disease
چکیده انگلیسی مقاله Background: Alzheimer's Disease (AD) is a neurodegenerative disorder, which is the most common cause of dementia in the elderly. Accumulation of β-amyloid plaques outside neurons is the most important pathological hallmark of AD, which is produced by cleavage of amyloid precursor protein by the Alzheimer's β-secretase (BACE1). Since BACE1 is a key enzyme in the formation of β-amyloid peptides, the purpose of this study was to assess the association between polymorphisms of G/C (rs638405) BACE1 gene with sporadic AD in Khuzestan, Isfahan and Fars provinces in Iran. Methods: Genotypes were determined by the PCR–Restriction Fragment Length Polymorphism (PCR–RFLP) technique in two groups including 89 sporadic AD patients and 73 healthy subjects. Results: The findings of the BACE1 G/C (rs638405) polymorphism revealed that there was no significant difference between AD patients and controls in men group; however, there was a weak difference in the frequency of CC genotype between patients and controls in women group (χ2=3.333, df=1, p=0.068). Conclusion: The results of this study suggest that the G/C (rs638405) polymorphism of BACE1 gene might not be related with sporadic AD in Khuzestan, Isfahan and Fars provinces in Iran. However, our results do not support a genetic risk factor of this polymorphism for developing AD in male group of this study.
