Furthermore, analysis of renal clear cell carcinoma showed that GNB1 was correlated with WASP family member 2 (WASF2), Neuropilin-1 (NRP1) and huntingtin interacting protein 1 (HIP1) of the vascular endothelial growth factor (VEGF) signaling pathway [15]. The gene discussed is NRP1; the disease is clear cell renal carcinoma.
