Of the 29 ERVs in the prognosticator, 25 contained elements (ERV1, HERVH-int, and ERVL–MaLR) that were previously shown to play a role in cancer [62,63] and four (ERV #1875, ERV #5137, ERV #5270, and ERVK-10) contained ERVK elements, which may play a role in prostate cancer patients [26,64,65]. This evidence concerns the gene LINC02154 and prostate cancer.
