Abstract: Interphase fluorescence in situ hybridization was used to detect common deletions in B-CLL patients as well as trisomy 12 and aberrations of IgH gene complex at 14q32.33 where we evaluated not only translocation-like signal pattern but also deletions. 120 (82%) patients showed genetic changes – del(13)(q14) 95 (62%), deletion of ATM gene 22 (15%), deletion of p53 gene 25 (17%) and trisomy 12 was proved in 18 (12%) cases. IgH rearrangements were detected in 45 (31%), split of the signals in 11 (8%), deletion of 3´segment flanking IgH gene in 5 (3%) and deletions of variable segment in 29 (20%) patients. Although deletions of 3´segment flanking IgH gene complex are supposed to have an adverse prognostic impact and the genetic background of variable segment deletions is believed to be most probably physiological, we assumed a detailed mapping of the 14q32.33 region will be needed to unravel these mysteries.
