NCIt definition : A fusion gene that results from a chromosomal rearrangement either t(3;3)(q21;q26)
or inv(3)(q21q26) which fuses the promoter sequences from the GATA2 gene on either
the 5' or 3' side of the coding sequence of the MECOM gene. This rearrangement is
associated with overexpression of the histone-lysine N-methyltransferase MECOM protein
and 3q21q26 syndrome-related leukemias.;
NCIt note : For this acute myeloid leukemia-associated fusion the involvment of the GATA2 gene
was originally mislocalized to the RPN1 gene.;
