SEPT2 is a new fusion partner of MLL in acute myeloid leukemia with t(2;11)(q37;q23)
We have identified a new mixed lineage leukemia ( MLL ) gene fusion partner in a patient with treatment-related acute myeloid leukemia (AML) presenting a t(2;11)(q37;q23) as the only cytogenetic abnormality. Fluorescence in situ hybridization demonstrated a rearrangement of the MLL gene and molecula...

description | We have identified a new mixed lineage leukemia (
MLL
) gene fusion partner in a patient with treatment-related acute myeloid leukemia (AML) presenting a t(2;11)(q37;q23) as the only cytogenetic abnormality. Fluorescence
in situ
hybridization demonstrated a rearrangement of the
MLL
gene and molecular genetic analyses identified a septin family gene,
SEPT2
, located on chromosome 2q37, as the fusion partner of
MLL
. RNA and DNA analyses showed the existence of an in-frame fusion of
MLL
exon 7 with
SEPT2
exon 3, with the genomic breakpoints located in intron 7 and 2 of
MLL
and
SEPT2
, respectively. Search for DNA sequence motifs revealed the existence of two sequences with 94.4% homology with the topoisomerase II consensus cleavage site in
MLL
intron 7 and
SEPT2
intron 2.
SEPT2
is the fifth septin family gene fused with
MLL
, making this gene family the most frequently involved in
MLL
-related AML (about 10% of all known fusion partners). The protein encoded by
SEPT2
is highly homologous to septins 1, 4 and 5 and is involved in the coordination of several key steps of mitosis. Further studies are warranted to understand why the septin protein family is particularly involved in the pathogenesis of
MLL
-associated leukemia. |
