Fig. 2From: Deletion 9p23 to 9p11.1 as sole additional abnormality in a Philadelphia positive chronic myeloid leukemia in blast crisis: a rare eventKaryotype and chromosomal aberrations were confirmed using molecular cytogenetic approaches. a FISH using probes for BCR (green) and ABL (red) showed 2 copies of BCR/ABL on Ph chromosome and on der(9), respectively. b FISH using probes for ST 9p (green) and ST 9q (red) showed; 1 green and 1 red signal on der(9); and 1 red signal on Ph chromosome and 1 green signal on der(9). c The deletion of CDKN2A was identified on the der(9). d The application of MCB 9 characterized the del(9)(p24p12) comprehensively.
