The difference of TMPRSS2-ERG fusion transcripts between KANSARL-positive and KANSARL-negative tumors is significant (Supplementary Table 7, Fisher's exact test, p<0.001), indicating that KANSARL fusion transcripts are associated with prostate cancer biomarker TMPRSS2-ERG fusion transcripts in the VPD tumor patients. This evidence concerns the gene ERG and prostate cancer.
