However, Saenz-Lopez et al. reported that the VEGF-A -2578, -1498, -634, and +936 polymorphisms were not correlated with clinicopathological characteristics or the prognosis of RCC [22], and Zhong et al. reported no association between the VEGF-A -1154 polymorphism and RCC progression [26]. Here, VEGFA is linked to renal cell carcinoma.
