The latency type III program is frequently found in EBV-associated PTLD, acute infectious mononucleosis (IM) and X-linked lymphoproliferative syndrome (XLP), in which the full spectrum of latent genes (EBNA1, EBNA2, EBNA3A, EBNA3B, EBNA3C, EBNA-LP, LMP1, LMP2A and LMP2B) are expressed [10]. This evidence concerns the gene PDLIM7 and X-linked lymphoproliferative disease.
