NCI Definition: Post-transplant lymphoproliferative disorder (PTLD) is a polyclonal (benign) or clonal (malignant) proliferation of lymphoid cells that develops as a consequence of immunosuppression in a recipient of a solid organ or bone marrow allograft. PTLDs comprise a spectrum ranging from early, Epstein-Barr virus (EBV)-driven polyclonal lymphoid proliferations to EBV-positive or EBV- negative lymphomas of predominantly B-cell or less often T-cell type. (WHO, 2001) [1]

Post-transplant lymphoproliferative disorders most frequently harbor alterations in TP53, MCL1, and CBL [2].

Most Commonly Altered Genes in Post-Transplant Lymphoproliferative Disorder

TP53 c.217-c.1178 Missense, TP53 R248Q, TP53 Mutation, TP53 Missense, and TP53 Exon 7 Mutation are the most common alterations in post-transplant lymphoproliferative disorder [2].
