NLRC4 inflammasomopathy

The NLRC4 inflammasomopathies comprise a growing autoinflammatory disease category that spans a broad clinical spectrum from cold urticaria to the autoinflammation with infantile enterocolitis (AIFEC). AIFEC is a rare autosomal dominant disease characterized by neonatal-onset enterocolitis, periodic fever, and fatal/near-fatal episodes of autoinflammation. It was shown that the disease is caused by gain-of-function mutations in NLRC4. NLRC4 protein is known to directly assemble inflammasomes that activate IL-1beta and IL-18.
