Abstract: | BackgroundLRP2 (also called megalin) plays a potential key role in the pathogenesis of Alzheimer's disease (AD). Recently, one genome-wide association study has revealed that the rs3755166 (G/A) polymorphism located in the LRP2 promoter is associated with development of AD in Caucasians, while there are no studies on the association LRP2 of with AD risk in Asians.MethodsTo evaluate the relationship between the rs3755166 polymorphism of the LRP2 gene and AD in the ethnic Chinese Han, we conducted a case-control study (n = 361, age > 50) to determine the prevalence of one common single-nucleotide polymorphism (SNP) of LRP2 (rs3755166) in patients with AD in Chinese population of Mainland China, and clarified whether this polymorphism is a risk factor for AD.ResultsThe prevalence of the minor allele (A) in the rs3755166 polymorphism was significantly different in AD patients and control subjects (P < 0.05). The rs3755166 polymorphism was associated with AD in the ethnic Chinese Han (OR = 1.378, 95% CI: 1.017-1.867, P = 0.039), and the results were not influenced by age, gender, or APOE status (P = 0.441, P = 0.94, P = 0.432, respectively).ConclusionOur data revealed the allele (A) of the rs3755166 polymorphism within LRP2 gene may contribute to AD risk in the Chinese Han Population. |
