    ABSTRACT: It has recently been shown that GAB2 alleles modify the risk for late-onset Alzheimer disease (LOAD) in apolipoprotein E (ApoE)epsilon4 allele carriers in a genome-wide association study. Some studies subsequently in Caucasians population, though not all, have demonstrated that GAB2 polymorphisms might be associated with LOAD susceptibility. The aim of this study is to evaluate the reported polymorphisms (rs2373115 and rs1385600) and GAB2 haplotypes (rs2373115-rs1385600) for an interaction with the ApoEepsilon4 allele in a cohort of Chinese LOAD. We conducted a case-control study in 292 LOAD and 227 non-demented controls from the Chinese Han population. Our study does not find any association between the two tested SNPs and GAB2 haplotypes and LOAD or any synergetic interaction between the SNPs and ApoE either. However, since the sample size required to show this point is large, our finding needs to be confirmed by a large independent sample of Chinese population.

    ABSTRACT: Saitohin (STH) is thought to be involved in the pathogenesis of many neurodegenerative diseases. Recent reports were inconclusive in showing that the Q7R polymorphism in the STH gene is associated with late-onset Alzheimer's disease (LOAD). We examined the Q7R polymorphism in 500 subjects (LOAD: 280; controls: 220) from Guangdong, China, by the Restriction Fragment Length Polymorphism method. Only one QR heterozygous and no RR homozygous variants were found. Our results suggest that the frequency of the R allele in the Han population is lower than that in Caucasian and African populations. The Q7R polymorphism is unlikely to contribute significantly to Alzheimer's disease susceptibility of the Han population in south China and the variation of the Q7R polymorphism among different ethnic groups might account for the varied clinical manifestations of some STH-related diseases.
