ICD-Morpho 9966/3 Myeloid and lymphoid neoplasms with PDGFRB rearrangement
ICD-Morpho 9975/3 Chronic myelogenous leukaemia, BCR-ABL1 positive; Myeloproliferative neoplasm, unclassifiable; Myelodysplastic/myeloproliferative neoplasm, unclassifiable
Atlas_Id 1326

Clinics and Pathology

Disease Atypical chronic myelogenous leukemia (a-CML) (BCR-ABL negative chronic myeloproliferative disease)
Epidemiology Only one case to date, a 79 yr old male patient
Prognosis The disease was sensitive to imatinib, but the patient developped resistance to imatinib and died 14 mths after diagnosis

Genes involved and Proteins

Gene NamePDGFRB (platelet-derived growth factor receptor, beta polypeptide)
Location 5q32
Protein PDGFRB is the receptor for PDGFB (platelet-derived growth factor-b); Ig like, transmembrane and tyrosine kinase domains; membrane tyrosine kinase; can homodimerize
Gene NameTP53BP1 (tumor protein p53 binding protein 1)
Location 15q15.3
Protein Component of the cellular response to DNA damage

Result of the chromosomal anomaly

Hybrid gene
Description 5' TP53BP1-3' PDGFRB; breakpoint in PDGFRB intron 10, identical to most PDGFRB breakpoints; exon 23 of TP53BP1 fused in frame to PDGFRB exon 11; reciprocal product not detectable
Fusion Protein
Description 247 kDa; composed of the N-term TP53BP1 including the coiled coil domains and the kinetochore binding domain from TP53BP1 fused to the transmembrane and the tyrosine kinase domains of PDGFRB C-term.
Oncogenesis The coiled coil domains from TP53BP1 may mediate PDGFRB homodimerization and constitutive activation of its tyrosine kinase activity; on the other hand, the DNA damage response of TP53BP1 may be perturbed.
