top SNP rs6812849 reached a p value of 2.99×10−7. Another two SNPs in the same region, rs7691872 and rs1503292, were the sixth and seventh most significant SNPs. The SNPs ranked as the eighth and ninth most significant were located in the introns of NDRG1 and GABBR2, respectively, with p values of 3.1 × 10−6 and 5.4 × 10−6. Compared with EAs, GWAS results for AAs were less remarkable; no SNPs had p < 1 ×10−6 (Table 3).
