KDR and rheumatoid arthritis: Paradowska-Gorycka et al first found that the VEGFR2 gene polymorphisms showed significant association with the risk of RA, and VEGFR2 rs2305948 SNP was associated with DAS-28 score, VAS score, number of swollen joints, mean value of CRP, suggesting an important role of VEGFR2 gene polymorphisms in the severity of RA.[15] In this study, we observed that TT genotype of rs11941492 C/T polymorphism was associated with a decreased risk of RA.
