editContent Update To WHO 5th Edition Classification Is In Process; Content Below is Based on WHO 4th Edition ClassificationThis page was converted to the new template on 2023-12-07. The original page can be found at HAEM4:Nodal Marginal Zone Lymphoma.
(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.)

Driver Gene | Fusion(s) and Common Partner Genes | Molecular Pathogenesis | Typical Chromosomal Alteration(s) | Prevalence -Common >20%, Recurrent 5-20% or Rare <5% (Disease) | Diagnostic, Prognostic, and Therapeutic Significance - D, P, T | Established Clinical Significance Per Guidelines - Yes or No (Source) | Clinical Relevance Details/Other Notes |
---|---|---|---|---|---|---|---|
EXAMPLE: ABL1 | EXAMPLE: BCR::ABL1 | EXAMPLE: The pathogenic derivative is the der(22) resulting in fusion of 5’ BCR and 3’ABL1. | EXAMPLE: t(9;22)(q34;q11.2) | EXAMPLE: Common (CML) | EXAMPLE: D, P, T | EXAMPLE: Yes (WHO, NCCN) | EXAMPLE:
The t(9;22) is diagnostic of CML in the appropriate morphology and clinical context (add reference). This fusion is responsive to targeted therapy such as Imatinib (Gleevec) (add reference). BCR::ABL1 is generally favorable in CML (add reference). |
EXAMPLE: CIC | EXAMPLE: CIC::DUX4 | EXAMPLE: Typically, the last exon of CIC is fused to DUX4. The fusion breakpoint in CIC is usually intra-exonic and removes an inhibitory sequence, upregulating PEA3 genes downstream of CIC including ETV1, ETV4, and ETV5. | EXAMPLE: t(4;19)(q25;q13) | EXAMPLE: Common (CIC-rearranged sarcoma) | EXAMPLE: D | EXAMPLE:
DUX4 has many homologous genes; an alternate translocation in a minority of cases is t(10;19), but this is usually indistinguishable from t(4;19) by short-read sequencing (add references). | |
EXAMPLE: ALK | EXAMPLE: ELM4::ALK
|
EXAMPLE: Fusions result in constitutive activation of the ALK tyrosine kinase. The most common ALK fusion is EML4::ALK, with breakpoints in intron 19 of ALK. At the transcript level, a variable (5’) partner gene is fused to 3’ ALK at exon 20. Rarely, ALK fusions contain exon 19 due to breakpoints in intron 18. | EXAMPLE: N/A | EXAMPLE: Rare (Lung adenocarcinoma) | EXAMPLE: T | EXAMPLE:
Both balanced and unbalanced forms are observed by FISH (add references). | |
EXAMPLE: ABL1 | EXAMPLE: N/A | EXAMPLE: Intragenic deletion of exons 2–7 in EGFR removes the ligand-binding domain, resulting in a constitutively active tyrosine kinase with downstream activation of multiple oncogenic pathways. | EXAMPLE: N/A | EXAMPLE: Recurrent (IDH-wildtype Glioblastoma) | EXAMPLE: D, P, T | ||

editv4:Gene Mutations (SNV/INDEL)The content below was from the old template. Please incorporate above.
Whole-exome sequencing (WES) study have identified mutations involved in NOTCH, nuclear factor κB (NF-κB), B-cell receptors and toll like receptor pathways . In one study, 16% (4/25) of cases identified a BRAF (V600E) mutation with associated strong IgD expression. In one of the four BRAF positive mutation, two non-hotspot mutations were detected (L597Q and N581I) which was previously found in BRAF V600 wild-type melanoma. In the same study, mutations of KMT2D (7/25, 28%), TET2 (5/25, 20%), and EZH2 (5/25, 20%) were among the more frequent mutated genes. CREBBP, TNFRSF14, FAS, TNFAIP3, KLF2, and CXCR4 mutations were also detected[2]. In another study, which investigated genetic lesions in 35 patients with NMZL, PTPRD mutations were found in 14.3% (5/35) of patients and PTPRD locus deletions were found in 5.7% (2/35) of patients[3]. Mutations were also identified in another study for NFKBIE and ITPR2 mutations involved in the NF-κB pathway and B-cell receptor mediated calcium signal pathway. However, in this study they did not find any PTPRD mutations or BRAF mutations, demonstrating the diverseness of the disease[4]. No BRAF mutations have yet to be identified in other studies on NMZL[2].
Other Mutations
Immunoglobulin genes are clonally rearranged consisting of mutated IGHV3 and IGHV4 family members, particularly IGHV4-34 and cases associated with hepatitis C use IGHV1-69[1].
