Although imatinib represents an attractive therapeutic agent for neoplasias associated with abnormal PDGFRbeta signaling, the low frequency of the TEL/PDGFRbeta and Hip1/PDGFRbeta fusion proteins in CMML suggests that its application to this disease maybe limited.
It has been shown previously that the Huntingtin interacting protein 1 gene (HIP1) was fused to the platelet-derived growth factor beta receptor gene (PDGFbetaR) in leukemic cells of a patient with chronic myelomonocytic leukemia.
We have previously reported that the Huntingtin interacting protein 1 (HIP1) gene is fused to the platelet-derived growth factor beta receptor (PDGFbetaR) gene in a patient with chronic myelomonocytic leukemia.
We report the fusion of the Huntingtin interactin protein 1 (HIP1) gene to the platelet-derived growth factor betareceptor (PDGFbetaR) gene in a patient with chronic myelomonocytic leukemia (CMML) with a t(5;7)(q33;q11.2) translocation.
