Previous GWA studies identified a SNP (rs4973341) in the CCL20 locus was significantly associated with PBC (P = 2.34 × 10−10) in a meta-analysis using European and North American PBC cohorts [11], but none of rs4973341 and SNPs in the shared haplotype with rs4973341 were included in the Human OmniZhongHua-8 Beadchip used in Han Chinese GWAS study. Here, CCL20 is linked to primary biliary cholangitis.
