Initially, we used the whole chromosome painting (WCP) probes for chromosomes 7 and 15 (Fig. 1b). Thus, we could narrow down the breakpoint between deletion 7p21 and 7p15, revealing the deletion of the ETV1 gene (Fig. 1c).

case_images: With multicolor-FISH, the complex karyotype was confirmed and refined as 47,XY,der(3)del(3)(p),der(4)t(4;5),der(7)t(7;15),+21c (Fig. 2a). Multicolor banding (MCB) was performed for chromosomes 1, 3, 4, 5, 7 and 15 (Fig. 2b), as described by Liehr and colleagues. The chromosomal rearrangements and the breakpoints involved in derivative chromosomes 1, 3, 4, 5, 7 and 15 were defined (Fig. 2c-e).
