In addition, by analyzing the expression of C11orf54 in several cancer tissue samples based on TCGA data using the GEPIA website, we found that C11orf54 had low expression in most cancer tissues, especially in KICH (Kidney Chromophobe), KIRP (Kidney renal papillary cell carcinoma), and SARC (Sarcoma; Supplementary Fig. 7). Here, BKGD is linked to chromophobe renal cell carcinoma.
