Description : Familial cold autoinflammatory syndrome is characterized clinically by recurrent attacks
of a maculopapular rash associated with arthralgias, myalgias, fever and chills, and
swelling of the extremities after exposure to cold. Despite the first description
of 'cold urticaria' (Kile and Rusk, 1940) the rash in most patients is nonpruritic
and nonurticarial. Rarely, some patients may also develop late-onset renal amyloidosis
(Hoffman et al., 2000). Overlapping syndromes also caused by mutation in the NLRP3
gene include Muckle-Wells syndrome (CAPS2; 191900), which has a high frequency of
amyloidosis and late-onset sensorineural deafness, and chronic neurologic cutaneous
and articular syndrome (CINCA, CAPS3; 607115), which shows earlier onset and a more
severe phenotype. - Genetic Heterogeneity of Familial Cold Autoinflammatory Syndrome
