To investigate polymorphisms of the vascular endothelial growth factor (VEGF) gene in patients with rheumatoid arthritis (RA) and their relationship to clinical features. ⋯ Our data suggested a trend of association between VEGF gene polymorphisms and RA, and patients who carried the haplotype GA of rs2010963 and rs833070 were more susceptible to RA. Our study was performed in a small population, and further studies in other populations are needed to confirm these results.
