Clinics and Pathology

Disease Anaplastic large cell lymphoma, ALK negative
Note Two available cases of t(6;12)(q22;q24) to date (Barbieri et al., 1984; Crescenzo et al., 2015). One case was a 39 year old patient (Barbieri et al., 1984).
Prognosis No data

Genes involved and Proteins

Note In one case of t(6;12)(q22;q24) a hybrid NCOR2/ROS1 was found (Crescenzo et al., 2015).
Gene NameNCOR2
Location 12q24.31
Protein This gene encodes a nuclear receptor co-repressor that mediates transcriptional silencing of certain nuclear receptors by promoting chromatin condensation, thus preventing access of the basal transcription. Aberrant expression of NCOR2 is associated with certain cancers.
Gene NameROS1
Location 6q22.1
Protein This proto-oncogene belongs to the subfamily of tyrosine kinase insulin receptor genes and expresses in a variety of tumor cell lines. ROS1 is an integral membrane protein with tyrosine kinase activity, that may function as a growth or differentiation factor receptor.

Result of the chromosomal anomaly

Hybrid gene
Fusion Protein
  Schematic of the structure of the NCOR2/ROS1 fusion. The N-term region of NCOR2 is fused to the intracytoplasmic region of ROS1.
Oncogenesis The chimeric NCOR2/ROS1 fusion may influence the transcriptional activity of the partner genes, perturbing transcription repression. This, in turn, may lead to a widespread derangement of several metabolic and signaling pathways ( STAT3), which concur to tumor transformation [Crescenzo et al, 2015; Tabbo et al, 2016].
