Additionally, this category includes pancreatogenic forms (after pancreatic surgery, after pancreatitis, pancreatic tumors, hemochromatosis, cystic fibrosis), rare infection-triggered (e.g., congenital rubella syndrome) and autoimmune forms other than type 1 diabetes (e.g., Stiffman syndrome, anti-insulin receptor antibodies, insulin autoimmune syndrome). Here, INSR is linked to pancreatitis.
