We could also confirm the detection in blood of other isoforms derived from fusion genes specific to different organs, such as: FOXP1::EIF4E3, ABI2::CYP20A1, and CTSD::IFITM10, related to breast adenocarcinoma [33,34,35,36]; HAVCR1::TIMD4 and JAK3::INSL3, related to kidney adenocarcinoma [34,36,37]; and HACL1::COLQ and SIDT2::TAGLN, related to lymph node nonneoplastic disorders [30,36]. Here, FOXP1 is linked to renal cell adenocarcinoma.
