Therefore, KCNJ14’s correlation with purity was investigated, and the result showed a significant correlation in 16 tumours, among which a significant positive correlation was found in 12 tumours, such as GBM, ESCA, STES, KIRP, STAD, PRAD, HNSC, LUSC, THYM, BLCA, ACC, and KICH, and a significant negative correlation was found in 4 tumours, such as LUAD, KIRC, and UVM (Figure 5D). Here, KCNJ14 is linked to neoplasm.
