inv(16)(p13.1q22), a pericentric inversion of chromosome 16, and the less common t(16;16)(p13.1;q22), a translocation involving the short arm of one chromosome 16 and the long arm of the other chromosome 16, define a distinctive cytogenetic subtype of acute myeloid leukemia. Both of these chromosome rearrangements result in the CBFB-MYH11 gene fusion. | |||
