Previous work has shown an association between the K variant of the butyrylcholinesterase (BCHE) gene and Alzheimer's disease (AD) in patients carrying the epsilon4 allele of ApoE. We attempted to replicate this finding in 181 UK white AD cases and 71 controls. No difference was found in BCHE-K genotypes (p=0.75) or alleles (p=0.70) between patients and controls. Moreover, despite a significant excess of ApoE epsilon4 in patients versus controls (p<0.0001), we found no evidence to support previous reports of an interaction between ApoE and BCHE-K (chi2=1.49, df=4, p=0.83).
先前的研究表明,在携带载脂蛋白E(ApoE)ε4等位基因的患者中,丁酰胆碱酯酶(BCHE)基因的K变体与阿尔茨海默病(AD)之间存在关联。我们试图在181例英国白人AD病例和71例对照中重复这一发现。患者和对照之间在BCHE-K基因型(p=0.75)或等位基因(p=0.70)方面未发现差异。此外,尽管患者中的ApoE ε4显著多于对照(p<0.0001),但我们没有发现证据支持先前关于ApoE与BCHE-K之间相互作用的报道(χ2=1.49,自由度=4,p=0.83)。
