The original prostate cancer study indicated [7] that the 14 prostate cancer samples harbored 38 tumor-specific chimeric transcripts, of which at least 5 are recurrent transcripts in Chinese population, including TMPRSS2-ERG, USP9Y-TTTY15, CTAGE5-KHDRBS3, RAD50-PDLIM4, and SDK1-AMACR. This evidence concerns the gene SDK1 and Familial prostate cancer.
