Revealing novel genomic insights and therapeutic targets for juvenile idiopathic arthritis through omics

Rheumatology (Oxford)Published Genome-wide association study meta-analysis

Authors' conclusion

Our identification of four novel JIA-associated genes, CD247, RHOH, COLEC10 and IRF8, broadens the novel potential drug repositioning opportunities.
