(a) The karyogram (GTG-banding) showing complex karyotype of the patient: 45,XY,-1, dup(1)(p32p34),der(3)t(1;3)(q12;q22),der(5)t(5;10)(q21;p11),der(9)t(4;9)(q32;p21),der(11)t(1;11)(p32;p13),del(12)(p13),der(16)t(6;16)(q22;p13)[10]/46,XY[15] (b,c,d) Results of FISH tests with probes: ETV6/RUNX1, BCR/ABL1 and KMT2A. FISH was performed on metaphases and interphase nuclei using probes (Cytocell Ltd., Oxford Gene Technology, Cambridge, United Kingdom) according to the manufacturer's recommendations. Images were captured by an Olympus BX41TF microscope equipped with a Jenoptik camera and analysed with Isis Software (MetaSystems)

case_images: GTG band staining (Fig. 1a) and fluorescence in situ hybridization (FISH) test were performed with the use of probes: BCR/ABL1, KMT2A, ETV6/RUNX1 (Vysis, Abbot Molecular, Illinois, USA). The arrangement from ETV6/RUNX1 probe suggested ETV6 deletion (Fig. 1b). The arrangement of signals from other probes used was correct (Fig. 1c and d). FISH tests (Fig. 3). Finally cytogenetic result was the following: 45,XY,-1,dup(1)(p32p34),der(3)t(1;3)(q12;q22),der(5)t(5;10)(q21;p11),der(9)t(4;9)(q32;p21),der(11)t(1;11)(p32;p13),del(12)(p13),der(16)t(6;16)(q22;p13)[10]/46,XY[15] (Fig. 4 and Table 1).
