Different ERG chromosomal translocations were detected in different tumor types, such as ERG-TMPSSR2 translocations in prostate cancer51, ERG-EWS translocations in Ewing’s sarcoma52 and ERG-FUS translocations in acute myeloid leukemia53. However, ERG chromosomal translocations or mutations were barely detected in ccRCC7. The gene discussed is EWSR1; the disease is neoplasm.
