Forty five cases carrying the t(2;11)(p21;q23) have been reported in the literature, mostly in myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). Some of these cases involve rearrangements of the the MLL gene (also known as KMT2A), on 11q23, which confers a more aggressive behavior in myeloid neoplasms. Several individual case reports, as well as series such as 19 cases reported by Bousquet et al., 2008 and 7 cases by Dvorak et al., 2014, describe myeloid neoplasms carrying the t(2;11)(p21;q23) without an MLL gene rearrangement, with possible prognostic implications. The authors of this paper describe two additional cases from their institution.
