The most frequent rearrangement found in patients with acute myeloid leukemia was the MLL-MLLT3 fusion (42%), followed by MLL-MLLT10 (23%), MLL-MLLT1 (8%), MLL-ELL (8%), MLL-MLLT4 (4%), and MLL-MLLT11 (4%).     ///    "The use of a combined strategy in the initial genetic evaluation of acute leukemia patients allowed us to characterize the pattern of MLL rearrangements in our institution, including our previous discovery of two novel MLL fusion partners, the SEPT2 and CT45A2 genes, and a very rare MLL-MLLT4 fusion variant.. "    ///    "In the remaining cases, a MLL-MLLT3 (27%), a MLL-MLLT1 (20%), or MLL-MLLT4 (7%) rearrangement was found. "
