{Reference Type}: Review {Title}: Identification of a variant in NLRP3 gene in a patient with Muckle-Wells syndrome: a case report and review of literature. {Author}: Liu J;Zhang R;Yi Z;Lin Y;Chang H;Zhang Q; {Journal}: Pediatr Rheumatol Online J {Volume}: 21 {Issue}: 1 {Year}: Feb 2023 10 {Factor}: 3.413 {DOI}: 10.1186/s12969-023-00795-x {Abstract}: BACKGROUND: Cryopyrin-associated periodic syndrome (CAPS), a rare genetic autoimmune disease, is composed of familial cold autoinflammatory syndrome (FCAs), Muckle-Wells syndrome (MWS), and neonatal onset multisystem inflammatory disease (NOMID). MWS is caused by dominantly inherited or de novo gain-of-function mutations in the NOD-like receptor 3 (NLRP3) gene. At present, there is no report about the variation of R262W in China.
METHODS: We reported a 3-year-old Chinese boy who had recurrent fever without obvious inducement, bilateral conjunctival congestion, and urticarial-like rash. Laboratory examination showed elevation in leukocyte count, neutrophil count, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) and serum amyloid protein (SAA) levels. Whole exome sequencing identified a missense variation c.784-786delinsTGG (p.R262W) in the coding region of the NLRP3 gene.
CONCLUSIONS: A classical variant of the NLRP3 gene in a patient with MWS was first reported in China.
