IL18BP

The protein encoded by this gene functions as an inhibitor of the proinflammatory cytokine, IL18. It binds IL18, prevents the binding of IL18 to its receptor, and thus inhibits IL18-induced IFN-gamma production, resulting in reduced T-helper type 1 immune responses. This protein is constitutively expressed and secreted in mononuclear cells. Elevated level of this protein is detected in the intestinal tissues of patients with Crohn's disease. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Feb 2011]

Hepatitis, fulminant viral (FVH):
An autosomal recessive form of fulminant viral hepatitis, a disease that strikes otherwise healthy individuals during primary infection with common liver-tropic viruses. FVH is characterized by severe liver destruction in the absence of a preexisting liver disorder, leading to encephalopathy within 8 weeks of the onset of the first symptoms.
