Similarly, SLC65A2 and SLC26A6 were significantly associated with poor prognosis in 3 tumor types including KICH and PRAD for both SLC genes, KIRP for SLC65A2, and ACC for SLC26A6. The highest log2FC was observed for SLC17A4 and SLC30A10, however both genes were negatively correlated with OS in one tumor (PRAD and ACC, respectively) (Figure 4A; Supplementary Table S4). Here, CCL21 is linked to adrenal cortex carcinoma.
