In addition, the SSBP2 (single-stranded DNA binding protein 2)–FER fusion (39) and the MAN2A1 (mannosidase alpha class 2A member 1)–FER fusion have also been identified in leukemia and hepatocellular carcinoma patients (40), respectively (Fig. 7A). Here, SSBP2 is linked to hepatocellular carcinoma.
