Detection of Autoimmune Regulator Gene Mutations in Children with Type 2 Autoimmune Hepatitis and Extrahepatic Immune-mediated Diseases

Autoimmune regulator gene mutations were identified in 3 children with type 2 autoimmune hepatitis and extrahepatic immune diseases, including 1 child with immune hepatitis recurrence after liver transplantation. These findings suggest that autoimmune regulator gene variants might predispose children to systemic autoimmune disease, a recurrence of immune disease, or both.
