| 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. |

| Genes involved and Proteins |
| Gene Name | PDE4DIP (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 Name | PDGFRB (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 |
| Description | 5' PDE4DIP - 3' PDGFRB; PDE4DIP (KIAA0477 isoform) fuses in frame PDGFRB exon 11 |
| Transcript | The reciprocal PDGFRB-PDE4DIP is not expressed |
| 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. |
| To be noted |
| Additional cases are needed to delineate the epidemiology of this rare entity: you are welcome to submit a paper to our new Case Report section. |
