Clinics and Pathology

Disease Myeloproliferative disorders (MPD) with eosinophilia (or chronic eosinophilic leukemia (CEL)) and B-cell acute lymphoblastic leukaemia (ALL)
Epidemiology 4 cases of MPD with eosinophilia, and 1 case of ALL; because the phenotypes are different, it may be that genes involved in this/these disease(s) are not similar; PDE4DIP and PDFRGB were found involved in MPD with eosinophilia (see below).
Clinics MPD cases were found in 3 infants (aged 5, 7, and 11 mths), and one young adult, aged 21 yrs; sex ratio was 1/1. The ALL case was a 13 yr old boy.
Prognosis One MPD case died 9 mths after diagnosis, another one was alive at 14 mths+, one was alive and well 7 yrs after diagnosis with IFN therapy, and one was found resistant to various treatments, including IFN therapy, until -because PDGFRB was found to be involved in the disease- imatinib was started and remission obtained. The ALL case experienced difficult remission, relapse, BM transplantation, CNS relapse; the parents finally refused further therapy and the patient died.


Additional anomalies Sole anomaly in each case.

Genes involved and Proteins

Gene NamePDE4DIP (phosphodiesterase 4D interacting protein (myomegalin))
Location 1q21.1
Note 1q22
Protein PDE4DIP codes for a protein called myomegalin; interacts with the cyclic nucleotide phosphodiesterase PDE4D; there ar at least 2 isoforms of myomegalin: KIAA0454 isoform and KIAA0477 isoform
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

Result of the chromosomal anomaly

Hybrid gene
Description 5' PDE4DIP - 3' PDGFRB; PDE4DIP (KIAA0477 isoform) fuses in frame PDGFRB exon 11
Transcript The reciprocal PDGFRB-PDE4DIP is not expressed
Fusion Protein
Description The first 905 amino acids of PDE4DIP, including the coiled-coil domains are fused to the transmembrane and the tyrosine kinase domains of PDGFRB.
