In our study, we noted that NRBP1 expression levels were significantly correlated with age, WHO grade, IDH status, and 1p/19q co‐deletion in the univariate analysis, consistent with previous findings showing upregulated NRBP1 expression in diverse cancers, including prostate cancer, bladder cancers, and triple‐negative breast cancers.13, 14, 18. Here, IDH1 is linked to urinary bladder carcinoma.
