Transformation of an Unclassified Myeloproliferative Neoplasm with a Rare BCR-JAK2 Fusion Transcript Resulting from the Translocation (9;22)(p24;q11)

Figure 1

Conventional cytogenetics (bone marrow) analysis revealing: (a) 46, XY, t(9;22)(p24;q11) in 60% of the metaphases: arrows indicate the balanced translocation between the short arm of the chr9 and the long arm of the chr22. (b) 47, XY, t(9;22)(p24;q11), +der(22) t(9;22)(q24;q11) in 10% of the metaphases: arrows indicate the chr9 and chr22 involved in the t(9;22)(p24;q11) and dotted arrow indicates the duplication of derived.
