- Abstract: PURPOSE: Stroke is the second leading cause of death and a major cause of morbidity and mortality worldwide. Evidence of variations in adiponectin(AdipoQ) genes that are associated with ischemic stroke has not been consistent, and it is unclear whether the same loci contribute to these associations in the Korean population. Using a Korean population, we tested ischemic stroke-associated AdipoQ markers. MATERIALS AND METHODS: In a preliminary genome-wide association study using 320 250 k Affymetrix NSP chips, AdipoQ was found to be associated with ischemic stroke in Koreans. To study of AdipoQ, a further 673 ischemic stroke patients and 267 unrelated individuals without a history of stroke or transient ischemic attack were examined in a case-control study. RESULTS: Six polymorphisms (rs182052G > A, rs16861205G > A, rs822391T > C, rs822396A > G, rs12495941G > T and rs3774261A > G) that had a minor allele frequency of over 1% were strongly associated with stroke (p < 0.05). Two of these, rs822391T > C and rs822396A > G showed this association on both dominant and additive logistic regression analysis after adjusting for age and sex. The haplotypes ht 1 (AGGCGG and AAGTAG) were significantly associated with susceptibility to stroke. CONCLUSION: Our findings show that polymorphisms in AdipoQ are associated with risk for ischemic stroke in the Korean population. This study lends further support to the putative role of AdipoQ in stroke.
