Novel mutation in NLRP3 Exon 7 results in sensorineural hearing loss without chronic inflammation.

Cryopyrin-associated periodic syndromes (CAPS) are a spectrum of autoinflammatory disesase with spontaneous activation of the NLRP3 inflammasome, leading to hypersecretion of IL-1b. To date, more than 90 mutations have been described in NLRP3,primarily in exon 3, leading to the autoinflammatory symptoms observed in CAPS. Here, we describe a family with autosomal dominantly inherited, unilateral sensorineural hearing loss, found to have a novel mutation in exon 7 of NLRP3.
