NLRP3 and CINCA syndrome: Interestingly, a somatic NLRP3 mutation (NLRP3: c.1709A>G (p.Tyr570Cys)) identical to that reported in a Neonatal Onset Multisystem Inflammatory Disease (NOMID, or Chronic Infantile Neurological, Cutaneous and Articular Syndrome, CINCA) case was also found in a patient with a clinical picture closely resembling Schnitzler’s syndrome, and without gammopathy and without bone pain like in our patient (22).
