Clinics and Pathology

Disease T-cell lymphomas
Epidemiology Four cases available to date: three peripheral T-cell lymphoma not otherwise specified (PTCL-NOS) (two male patients aged 20 and 63 yrs and one female patient aged 63 yrs), and one angioimmunoblastic T-cell lymphoma (Lepretre et al., 2000; Almire et al., 2007; Shin et al., 212).
Other features Recently, the cell line T8ML-1 with t(14;19) TRA/NECTIN2 was established from a 64-year old female patient diagnosed with fatal PTCL-NOS (Ehrentraut et al., 2017).

Cytogenetics

Cytogenetics Morphological The karyotype was complex in all four cases.

Genes involved and Proteins

Gene NameTRA (T cell Receptor Alpha)
Location 14q11.2
Gene NameNECTIN2 (nectin cell adhesion molecule 2)
Location 19q13.32
Note NECTIN2 is also called PVRL2 (poliovirus receptor-related 2).
Protein NECTIN2 is a cell membrane protein involved in immune checkpoint, part of the TIGIT-PVR/PVRL2 axis. NECTIN2 is composed of a signal peptide (amino acids (aa) 1-31), an extracellular domain (aa 32-360), a transmembrane domain (aa 361-381), and a cytoplasmic domain (aa 382-538). NECTIN2 also interacts with PVRIG CD226, CD96 to stimulate or inhibit lymphocyte cell signaling (Stamm et al., 2018; Whelan et al., 2019).

Result of the chromosomal anomaly

Hybrid gene
Note On chromosome 19, there was a cluster of breakpoints in the NECTIN2 gene region, 130 kb downstream of BCL3. The breakpoints on chromosome 14 were located in theTRAJ region (Almire et al., 2007).
  
Fusion Protein
Oncogenesis NECTIN2 was highly expressed in the t(14;19)(q11;q13)-positive tumors.
  

To be noted

Additional cases are needed to delineate the epidemiology of this rare entity:
