They found that the VEGFR2 rs1870377 A/T, and rs2305948 G/A polymorphisms were associated with an increased risk of RA, while VEGFR2 rs2071559 T/C polymorphism was related to a decreased risk of RA.[15] In addition, they observed that rs2305948 G/A polymorphism showed a significant positive association with the severity of RA.[15] However, they did not explore the relationship between VEGFR2 rs11941492 C/T polymorphism and RA risk. Here, KDR is linked to rheumatoid arthritis.
