EAF2 and acute myeloid leukemia: Studies initially identified EAF1 and EAF2/U19 (Up-regulated gene 19) through their association with ELL (Eleven-nineteen lysine-rich leukemia), a fusion partner of MLL in the t (11; 19) (q23; p13.1) chromosomal translocation associated with acute myeloid leukemia [3], [4], while an independent study simultaneously identified EAF2/U19 through its up-regulation by androgen in the rat prostate [5].
