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

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 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 NameCCDC88C (coiled-coil domain containing 88C)
Location 14q32.11
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
