Insertions in the vicinity of Jdp2 are not limited to retroviral models of T-ALL; recent studies of T-ALL initiated by the Sleeping Beauty transposon have also identified a shared integration site at the Jdp2 promoter and have shown that the inserted transposon drives Jdp2 overexpression (van der Weyden et al., 2013). This evidence concerns the gene JDP2 and acute lymphoblastic leukemia.
