Frequency and clinical impact of ETV6/RUNX1, AF4-MLL, and BCR/ABL fusion genes on features of acute lymphoblastic leukemia at presentation..     ///    "Abnormal genes detected were BCR/ABL1 major transcript in 5 (12.5%), ETV6/RUNX1 in 2 (5.0%), MLL/AF4 none and none of the patients had more than one fusion gene. "    ///    "Three major translocations (ETV6-RUNX1, BCR-ABL, and AF4-MLL) in acute lymphoblastic leukemia (ALL) have been shown to affect treatment outcome. "    ///    "Presence of fusion the genes BCR/ABL1, ETV6/RUNX1, and MLL/AF4 does not have any impact on the clinical and laboratory features of ALL at presentation.. "
