In the present paper, we report a molecular cytogenetic study of 1q abnormalities associated with t(8;14)(q24;q32) in an adult common B acute lymphoblastic leukemia case with FAB-L2 morphology. The use of appropriate molecular cytogenetic probes allowed us to detect 13 different subclones showing heterogeneous chromosome 1 abnormalities. A complex pattern of rearrangements consisting of translocations, duplications, and inversions was observed. Breakage-fusion-bridge cycle and jumping translocation are hypothesized to have been involved in generating the large number of aberrations we detected.

Abstract
In the present paper, we report a molecular cytogenetic study of 1q abnormalities associated with t(8;14)(q24;q32) in an adult common B acute lymphoblastic leukemia case with FAB-L2 morphology. The use of appropriate molecular cytogenetic probes allowed us to detect 13 different subclones showing heterogeneous chromosome 1 abnormalities. A complex pattern of rearrangements consisting of translocations, duplications, and inversions was observed. Breakage-fusion-bridge cycle and jumping translocation are hypothesized to have been involved in generating the large number of aberrations we detected.File in questo prodotto:
