p53-Binding Protein 1 Is Fused to the Platelet-Derived Growth Factor Receptor β in a Patient with a t(5;15)(q33;q22) and an Imatinib-Responsive Eosinophilic Myeloproliferative Disorder

Abstract excerpt

We describe the fusion of TP53BP1 to PDGFRB in a patient with a chronic myeloid leukemia-like disorder associated with eosinophilia and a t(5;15)(q33;q22). TP53BP1 encodes 53BP1, a p53-binding protein that plays a role in cellular responses to DNA damage. The 53BP1-PDGFRbeta fusion protein is predicted to retain the kinetochore-binding domain of 53BP1 fused to the transmembrane and intracellular tyrosine kinase...
