  1. OR, odds ratio; 95%CI, 95% confidence interval. Pper value, p value with 10,000 times permutation test. The haplotypes with frequencies lower than 5% excluded from analysis. Block 1**, the two SNP, rs6529901 and rs5916397, was in relatively high LD with D' > 0.8 and regarded as a block for multiple-marker analysis in this study. Significant p-values are indicated in bold.
