AIH is a fairly uncommon, non-resolving, chronic inflammatory liver disease characterized by hypergammaglobulinemia (elevated IgG), autoantibodies such as anti-smooth muscle antibody (anti-SMA), anti-nuclear antibody (ANA), and anti-liver kidney microsome (anti-LKM), as well as interface hepatitis on histology [1]. Here, SMN1 is linked to autoimmune hepatitis.
