VCGG channels, including CACNA1C, CACNA1D, CACNA1F, CACNA1E, CACNA1A, CACNA1G, CACNA1I, showed significantly higher expression in KIRC than normal cases, whereas CACNA1S and CACNA1H showed higher expression in normal than tumor cases (Figure 2B). The gene discussed is CACNA1D; the disease is neoplasm.
