Abstrakt: Objectives: To investigate whether the functional variant Q63R of the cannabinoid 2 (CB2) receptor is associated with susceptibility to oligo/poly-articular juvenile idiopathic arthritis (JIA) and with its clinical features. Method: A total of 171 Italian children with oligoarticular/rheumatoid factor negative poly-articular JIA and 600 healthy controls were enrolled in the study and genotyped. Results: A significant difference in genotype distribution of the CB2 Q63R variant ( CNR2 rs35761398) between oligo/poly-articular JIA patients and controls was found ( p = 0.001). The R63 variant was associated with increased rates of relapse ( p = 0.0001). Conclusions: This study indicates that the CB2 receptor contributes to susceptibility to oligo/polyarticular JIA and to the severity of its clinical course. [ABSTRACT FROM AUTHOR]
