In addition, significant abnormal expressions of the eight chosen DEMs in the model group, including IFNG, TBX21, IL17RA, IL4RA, IL10, RUNX1, RORC and FOXP1, were also detected with qRT‐PCR assay, which indicated that these genes are closely related to the incidence of AIH. This evidence concerns the gene IL17RA and autoimmune hepatitis.
