Using a case-control genetic approach, we have identified a SNP (rs10507391) in ALOX5 gene, previously associated with an increased risk of stroke, as a novel genetic risk factor for AD.
The interaction between rs10507391 and rs776746 increases the susceptibility to ischemic stroke and is associated with atherothrombotic events in stroke patients.
Eight variants in five candidate genes were examined for the risk of stroke, including the SG13S32 (rs9551963), SG13S42 (rs4769060), SG13S89 (rs4769874), and SG13S114 (rs10507391) variants of the 5-lipoxygenase activating protein (ALOX5AP) gene, the G860A (rs751141) variant of the soluble epoxide hydrolase (EPHX2) gene, the A1075C (rs1057910) variant of the CYP2C9*2 gene, the C430T (rs1799853) variant of the CYP2C9*3 gene, and the A6986G (rs776746) variant of the CYP3A5 gene.
Haplotype-based association analysis of block 2 involving rs10507391 and rs12429692 revealed that the decreased risk of stroke was significantly associated with haplotype AA (OR, 0.66; 95% CI, 0.46-0.95).
