Overview

The exact pathogenesis of cryopyrin-associated periodic syndrome is not fully understood.


Pathophysiology

Physiology

Pathogenesis

  • The exact pathogenesis of cryopyrin-associated periodic syndrome is not completely understood.

Genetics

  • Cryopyrin-associated periodic syndrome is transmitted in the autosomal dominant pattern.[1][2]
  • NLRP3 gene encoding a protein called cryopyrin (also known as nacht domain-, leucine-rich repeat- and pyrin domain-containing protein 3 [NALP3] or pyrin domain-containing apoptotic protease activating factor 1-like protein [PYPAF1] involved in the pathogenesis of this disorder.
  • Cryopyrin is derived from the Greek words for icy cold and fire. The recurrent episodes of this disease are usually triggered by cold.

Associated Conditions

  • Conditions associated with Familial Cold Autoinflammatory Syndrome (FCAS) include:[3]
    • Mild hearing loss
  • Conditions associated with Muckle-Wells Syndrome include:[4]
    • Hearing loss
    • Secondary amyloidosis
  • Conditions associated with Neonatal Onset Multisystem Autoinflammatory Disease (NOMID) include:[5][3]
    • Developmental delay
    • Seizure
    • Hydrocephalus
    • Chronic aseptic meningitis
    • Uveitis
    • Pericarditis
    • Destructive arthropathy
    • Secondary amyloidosis
