 An acute myeloid leukemia was suspected of having a t(8;16)(p11;p13) resulting in a KAT6A-CREBBP fusion because the bone marrow was packed with monoblasts showing marked erythrophagocytosis.     ///    Comparison between karyotyping-FISH-reverse transcription PCR and RNA-sequencing-fusion gene identification programs in the detection of KAT6A-CREBBP in acute myeloid leukemia..     ///    The leukemic cells were examined in two ways to find out whether a cryptic KAT6A-CREBBP was present.     ///    RT-PCR followed by Sanger sequencing of the amplified product showed that a chimeric KAT6A-CREBBP transcript was present in the patients bone marrow.     ///    FISH analysis indicated the presence of a KAT6A/CREBBP chimera.
