Detection of a novel CBFB-MYH11 fusion transcript in acute myeloid leukemia M1 with inv(16)(p13q22)
Acute myeloid leukemia (AML) with an inv(16)(p13q22) or t(16;16)(p13;q22) chromosomal abnormality represents one of the most common subtypes of de novo cases. These chromosomal rearrangements result in multiple CBFB-MYH11 fusion transcripts, with type-A being the most frequent. We here describe a unique case of de novo AML-M1, with inv(16)(p13q22), leading to an unusual CBFB-MYH11 fusion transcript, and der(7)t(7;11)(q31;q21). The fusion transcript involves a CBFB exon 5 with a breakpoint at nucleotide 754, an insertion of a 13-bp sequence of CBFB intron 5 at the fusion point, and the MYH11 exon 27 with a breakpoint at nucleotide 3464.
