OBJECTIVE
Mitochondrial dysfunction is a prominent and early feature of Alzheimer's disease (AD). The morphologic changes observed in the AD brain could be caused by a failure of mitochondrial fusion mechanisms. The aim of this study was to investigate whether genetic polymorphisms of two genes involved in mitochondrial fusion mechanisms, optic atrophy 1 () and mitofusin 2 (), were associated with AD in the Korean population by analyzing genotypes and allele frequencies.
METHODS
One coding single nucleotide polymorphism (SNP) in the , rs1042837, and two coding SNPs in the , rs7624750 and rs9851685, were compared between 165 patients with AD (83 men and 82 women, mean age 72.3±4.41) and 186 healthy control subjects (82 men and 104 women, mean age 76.5±5.98).
RESULTS
Among these three SNPs, rs1042837 showed statistically significant differences in allele frequency, and genotype frequency in the co-dominant 1 model and in the dominant model.
CONCLUSION
These results suggest that the rs1042837 polymorphism in may be involved in the pathogenesis of AD.
目的
线粒体功能障碍是阿尔茨海默病（AD）的一个突出且早期的特征。AD大脑中观察到的形态学变化可能是由线粒体融合机制的失败引起的。本研究的目的是通过分析基因型和等位基因频率，调查参与线粒体融合机制的两个基因，即视神经萎缩1（OPA1）和线粒体融合蛋白2（MFN2）的基因多态性是否与韩国人群中的AD相关。
方法
比较了165例AD患者（83名男性和82名女性，平均年龄72.3±4.41岁）和186名健康对照者（82名男性和104名女性，平均年龄76.5±5.98岁）中OPA1基因的一个编码单核苷酸多态性（SNP），rs1042837，以及MFN2基因的两个编码SNP，rs7624750和rs9851685。
结果
在这三个SNP中，rs1042837在等位基因频率、共显性模型1和显性模型的基因型频率上显示出统计学上的显著差异。
结论
这些结果表明，OPA1基因中的rs1042837多态性可能参与了AD的发病机制。
