Finally, patients 7 and 8 had acute hepatitis but did not meet the criteria for AIH; their liver tests normalized without the need for immunosuppression and they showed HLA DRB1*11, without an HLA strongly associated with AIH in Caucasians (i.e., HLA DRB1*03, HLA DRB1*07, HLA DRB1*13 and HLA DRB1*14). The gene discussed is HLA-DRB1; the disease is autoimmune hepatitis.
