Among all 33 cancer types, a significant positive correlation was found between ATP5B CNV and the expression level in 28 cancer types (only no correlations for ACC, CHOL, KICH, KIRC, and TGCT) (Supplementary Table 1), including the breast cancer (r = 0.38, p = 9.5e-38) (Figure 1C). Here, ATP5F1B is linked to cancer.
