The results showed that 25 genes were significantly associated with the overall survival of Wilms tumor, namely ADRA2A, BCL6, CA10, CCNA1, CTHRC1, DGKD, EPB41L4B, ERRFI1, GALNT3, JAM2, LRRC40, MTF2, NCEH1 NEBL, OSBPL3, PDS5B, PDSS1, RFX3, ROR1, RTKN2, SLAIN1, SPTLC3, TICAM1, TUBGCP3, and ZFP36L2 (see Table 1). This evidence concerns the gene RTKN2 and Nephroblastoma.
