results hla-drb1*07 (rr 5.3, p = 0.0008) and hla-drb1*08 (rr n.c. p = 0.0005) were significantly associated with the risk of pbc development. patients younger than 45 years had significantly higher alanine aminotransferase (p = 0.038) and alkaline phosphatase levels (p = 0.047) than older cases. in comparison to non-cc rs12979860, patients with cc rs12979860 genotype showed an early histologica...
