The molecular analysis was performed on the cDNA level, with the restriction analysis of PCR products (FLT3-TKD), conventional PCR (MLL-PTD, NPM1mut, FLT3-ITD) and quantification RT-PCR method (expression of fusion transcripts, BAALC, WT1).     ///    "Further analysis revealed FLT3-ITD in 5/20 (25%), FLT3-TKD in 3/20 (15%), NPM1mut in 2/20 (10%) and MLL-PTD in 1/20 (5%), overexpression of WT1 gene in 15/20 (75%) and overexpression of BAALC in 13/20 (65%) patients.
