Conversely, FMR1 was downregulated in glioblastoma multiforme (GBM, P < 0.05), kidney clear cell carcinoma (KIRC, P < 0.001), kidney papillary cell carcinoma (KIRP, P < 0.001), prostate adenocarcinoma (PRAD, P < 0.001), and uterine corpus endometrial carcinoma (UCEC, P < 0.001). Here, FMR1 is linked to clear cell renal carcinoma.
