OTULIN-related autoinflammatory syndrome (ORAS)

Disease ID:1177
Name:OTULIN-related autoinflammatory syndrome (ORAS)
Associated with:1 target
A potentially fatal inherited autoimmune disease. Premature newborns display severe idiopathic inflammatory symptoms, developing repeated episodes of systemic inflammation (diarrhea, elevated serum C-reactive protein) without evidence of infection. The affected babies develop painful swollen joints, elevated immunoglobulin levels and serum autoantibodies.


Role:  Faliure of otulin deubiquitinase activity results in spontaneous and uncontrolled immune system activation, leading to death if untreated.
Drugs:  The anti-TNFα antibody infliximab resolves ORAS symptoms, although it is not yet approved for this condition (August 2016). It is approved as a therapy for other autoimmune and inflammatory diseases, including rheumatoid arthritis and Crohn's disease.
