BACKGROUND: Several genome wide screens and candidate gene studies have implicated the chromosome 12p13 locus as possibly harboring genetic variants predisposed to late-onset Alzheimer's disease (LOAD). Recently, the strongest significant association was reported for the single nucleotide polymorphism (SNP) rs11610206 on chromosome 12q13 in an independent genome-wide association study (GWAS) in Caucasians.
METHODS: We investigated whether the SNP on chromosome 12q13 was associated with LOAD in a Han Chinese population. The common rs11610206 SNP on chromosome 12q13 was genotyped using MALDI-TOF mass spectrometry in 322 patients with LOAD and in 391 healthy controls matched for sex and age.
RESULTS: Patients with LOAD had higher frequencies of T allele (56.0% versus 49.2%) compared with controls [odds ratio (OR)=1.45, 95% confidence intervals (CI)=1.08-1.95, and P=0.01]. After stratification by APOE ε4-carrying status, the T allele of rs11610206 was significantly associated with LOAD only in APOE ε4 allele carriers (OR=2.05, 95% CI=1.21-3.47, and P=0.007). Furthermore, multivariate logistic regression analysis showed that the TT genotype carriers demonstrated a 1.52-fold risk when compared with (TC+CC) genotype carriers (OR=1.52, 95% CI=1.07-2.17, and P=0.02).
CONCLUSIONS: This study demonstrates an association of rs11610206 polymorphism locus on chromosome 12q13 with risk for LOAD in Han Chinese.
