“…Twenty-seven SNPs of twelve genes with a minor allele frequency > 0.05 in Han Chinese were selected. These 27 SNPs in 12 chemokine genes, included 4 SNPs (rs1024610, rs1024611, rs13900, and rs4586) of CCL2 [21, 22], 5 SNPs (rs4251719, rs2306630, rs2107538, rs9355610, and rs2280788) of CCL5 [12, 23, 24], 1 SNP (rs854680) of CCL16 [25], 2 SNPs (rs223828 and rs223895) of CCL17 [26–28], 3 SNPs (rs951005, rs2492358, and rs2812378) of CCL21 [29–31], 1 SNP (rs4359426) of CCL22 [32], 2 SNPs (rs2302004 and rs2302005) of CCL24 [33], 3 SNPs (rs2227306, rs2227543, and rs4694178) of CXCL8 [34], 2 SNPs (rs2276886 and rs2869460) of CXCL9 [14, 35], 1 SNP (rs2869462) of CXCL10 [35], 2 SNPs (rs1801157 and rs2839693) of CXCL12 [13, 15], and 1 SNP (rs2277680) of CXCL16 [36]. We excluded rs1024611 of CCL2 , since a study concerning this gene had been reported previously by our group [18].…”
