NOD2-associated autoinflammatory disease

NOD2-associated diseases. NAID
Definition: NOD2 is an intracellular microbial sensor of the innate immune system that can act as a potent activator and regulator of inflammation.
Mutations in the gene encoding NOD2 in humans have been associated with Crohn’s disease (CD), Blau syndrome (BS), and early onset sarcoidosis (EOS).
These diseases have in common features of dysregulated inflammation, but have very distinct phenotypes, which have been hypothesized to result from either loss-of-function (CD) or gain-of-function (BS/EOS) mutations.
early onset sarcoidosis
- systemic inflammation
- disseminated granulomatous disease
- granulomatous arthritis
- unusual gastrointestinal tract granulomas.
