Concerning the associations between the expression of WDR43 and PFI (Figure S1C, Supplemental Digital Content, http://links.lww.com/MD/N284), we explored that high expression of WDR43 negatively affected patients’ PFI in pheochromocytoma and paraganglioma, UCEC, LIHC, KIRC, KIRP, ACC, mesothelioma and KICH. This evidence concerns the gene WDR43 and paraganglioma.
