Haematolymphoid Tumours (WHO Classification, 5th ed.)

editContent Update To WHO 5th Edition Classification Is In Process; Content Below is Based on WHO 4th Edition Classification
This page was converted to the new template on 2023-12-07. The original page can be found at HAEM4:Polymorphic Post-Transplant Lymphoproliferative Disorders.

Note: encompassing polymorphic PTLD, other iatrogenic immunodef-assoc lympho disorders, among others

(General Instructions – The focus of these pages is the clinically significant genetic alterations in each disease type. This is based on up-to-date knowledge from multiple resources such as PubMed and the WHO classification books. The CCGA is meant to be a supplemental resource to the WHO classification books; the CCGA captures in a continually updated wiki-stye manner the current genetics/genomics knowledge of each disease, which evolves more rapidly than books can be revised and published. If the same disease is described in multiple WHO classification books, the genetics-related information for that disease will be consolidated into a single main page that has this template (other pages would only contain a link to this main page). Use HUGO-approved gene names and symbols (italicized when appropriate), HGVS-based nomenclature for variants, as well as generic names of drugs and testing platforms or assays if applicable. Please complete tables whenever possible and do not delete them (add N/A if not applicable in the table and delete the examples); to add (or move) a row or column in a table, click nearby within the table and select the > symbol that appears. Please do not delete or alter the section headings. The use of bullet points alongside short blocks of text rather than only large paragraphs is encouraged. Additional instructions below in italicized blue text should not be included in the final page content. Please also see Author_Instructions and FAQs as well as contact your Associate Editor or Technical Support.)

Gene Rearrangements

Cytogenetic abnormalities are uncommon in P-PTLD being present in approximately 15% of cases. [1]

Clonally rearranged Immunoglobulin (IG) genes IGH / IGK / IGL may be detected.

Gene Mutations (SNV/INDEL)

The frequency of mutations in P-PTLD is lower, and variants seen are less deleterious, when compared to those seen in monomorphic PTLD. [6] [7] Mutations in BCL6 are reported in up to 50% of P-PTLD cases. [8]

Epigenomic Alterations

Hypermethylation of O6-Methylguanine-DNA Methyl-Transferase (MGMT) is reported in 75% of P-PTLD [20]. MGMT is involved in DNA repair.

Hypermethylation of SHP1 is observed in 75% of P-PTLD. [20] The SHP1 gene is located on chromosome 12p13 and encodes the SHP1 protein. The protein is expressed in hematopoietic cells and potentiates its negative effect on cell cycle regulation by inhibiting the JAK/STAT pathway.

Genetic Diagnostic Testing Methods

Conventional cytogenetics, FISH, NGS

Familial Forms

Not known

Additional Information

Separate lesions may contain distinct and different clonal populations. [21]

Significant T-cell clones are not expected.

EBV terminal repeat analysis is the most sensitive method for detection of clonal populations in EBV+ cases.

P-PTLD is similar to non-germinal center monomorphic PTLD, when assessed using gene expression profiling. [1][2]
