HLA-DRB1 and primary biliary cholangitis: Data show that roles of these HLA-class II alleles in PBC development were quite consistent between Juran’s study and our study which suggested that HLA-DQB1*0402 and HLA-DRB1*0801 contribute to the PBC susceptibility and that conversely, HLA-DQB1*0301, HLA-DRB1*1101, and HLA-DRB1*1501 were protective alleles against PBC.
