Additionally, overexpression of SLC35G2 (TMEM22) and RAB37 genes in ccRCC tumors was observed [27, 28] and experiments on RCC cell lines implied that the SLC35G2/RAB37 complex was likely to play a crucial role in growth of RCC [29]. The gene discussed is SLC35G2; the disease is nonpapillary renal cell carcinoma.
