Among these, IL12A, IL12RB2, IRF5, TNPO3, DENND1B, SPIB, TNFAIP2, CXCR5, CLEC16A, RAD51L1, IRF8, RPS6KA4, MAP3K7IP1, TNFRSF1A, PLCL2, ELMO1, and ARF7 played an important role in the morbidity of PBC in European ancestries, while TNFSF15 and POU2AF1 were unique in Japanese ancestries, and CD80, IKZK3, Il7R, NFKB1, and STAT4 were proved to be associated with PBC in both races. This evidence concerns the gene STAT4 and primary biliary cholangitis.
