Higher BAMBI expression was associated with prolonged overall survival in 4 tumor types, including kidney renal clear cell carcinoma (P = 0.011), kidney renal papillary cell carcinoma (P = 0.045), pheochromocytoma and paraganglioma (P = 0.019), and uterine corpus endometrial carcinoma (P = 0.041) (Supplemental Figure 1A; supplemental material available online with this article; https://doi.org/10.1172/JCI172919DS1). This evidence concerns the gene BAMBI and pheochromocytoma.
