Abstract

Background. NLRP3 gene is located in chromosome 1 and encodes a pyrin-like protein. Mutations in this gene are associated with an autoinflammatory disease, called cryopyrin-associated periodic syndrome (CAPS). Case Presentation. We report a 1-year-old boy who had recurrent urticarial rash since birth and joint pain and swelling. He had a missense mutation c.G1060 T (p.A354S) in exon 5 of the NLRP3 gene which was detected by whole exome sequencing. Conclusion. A novel variant was found in the NLRP3 gene which has not been reported by now. © 2021 Mahdieh Vahedi et al.
