摘要: We report a NUMA1-PDGFRB fusion in myeloproliferative neoplasm with eosinophilia 61-year old man, response to imatinib mesylate therapy. A t(5;11) chromosome translocation involving bands 5q32 and 11q13.4 was identified by metaphase analysis, rearrangement of the platelet-derived growth factor receptor beta (PDGFRB) gene on demonstrated FISH using PDGFRB break-apart probe set. Bacterial artificial (BAC) mapping partner narrowed breakpoint at 150 kb genomic region containing three genes, including NUMA1. Mate pair sequencing analysis fusion. The protein includes coiled-coil domains nuclear mitotic apparatus 1 (NuMA1, involved homodimerization heteroassociation) tyrosine kinase PDGFRB. Diverse rearrangements have been myeloid lymphoid neoplasms eosinophilia, but (NUMA1) has previously reported human malignancy only one instance, NUMA1-RARA caused t(11;17) patient acute promyelocytic leukemia. is second instance NUMA1, encoding an element apparatus, cancer.
