t(7;11)(p15;p15) Chronic myeloid leukaemia developed into blastic transformation showing a novel NUP98/HOXA11 fusion.
We encountered a patient with Philadelphia-negative chronic myeloid leukaemia, with t(7;11)(p15;p15), in whom acute leukaemia phase (acute myeloid leukaemia-M2 morphology) developed within a short period. We detected a novel gene fusion between NUP98 and HOXA11 both in the chronic phase and in the acute leukaemia phase in this case. Although it is well known that a fusion of NUP98-HOXA9 in myeloid malignancies is created by the t(7;11)(p15;p15), this case suggests the possibility that HOXA11 might be another partner gene for NUP98 in t(7;11)(p15;p15) leukaemia.
