Identity

ICD-Topo C420,C421,C424 BLOOD, BONE MARROW, & HEMATOPOIETIC SYS
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 1379

Clinics and Pathology

Disease Atypical chronic myeloid leukemia (a-CML)
Epidemiology Only one case to date with ascertainment of the genes involved (another case was a 18 yr old female patient with a M2 acute myeloid leukemia (AML) and a t(7;11)(p15;p15); the t(5; 14) appeared at relapse, 5 mths before death, 27 mths after diagnosis).
Clinics The sole case of t(5;14)(q33;q32) with certain PDGFRB/KIAA1509 involvement was a 42 yr old male patient, BCR-ABL negative, treatad with imatinib, and maintained in complete remission 18 mths after diagnosis.

Genes involved and Proteins

Gene Name PDGFRB
Location 5q33
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 Name CCDC88C
Location 14q32
Protein poorly known; 1935 amino acids; possess a coiled coil domain.

Result of the chromosomal anomaly

Hybrid gene
Description 5' KIAA1509-3' PDGFRB; breakpoint in PDGFRB intron 10, identical to most PDGFRB breakpoints
  
Fusion Protein
Description 934 amino acids composed of the 355 amino acids from KIAA1506 in N-term and 579 amino acids from PDGFRB C-term
Oncogenesis the coiled coil domain may mediate PDGFRB homodimerization and constitutive activation
  

To be noted

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