The translocation t( I I ; I4)(q I3;q32) has been described in a spectrum of B-lymphoproliferative diseases and involves a putative oncogene, BCLI, which maps t o chromosome band I lq13. Recent evidence indicates that this abnormality may delineate particular subtypes of lymphoma, such as intermedia

Abstract
In three patients with nonβHodgkin lymphomas and in one cell line (HPLβHod) derived from pleural effusion cells of a patient with Hodgkin's disease, rearrangements of the long arm of chromosome No. 14(14q) were observed. These rearrangements appeared to be consistently associated with a 14q translocation, suggestive of occurrence of a break at 14q13. The translocation in an individual case could occur with 1p, 2q, 4q, and another 14q. A 14q13 translocation may be comparable with a 14q32 translocation, which has often been observed in various types of lymphoid malignancy.

Chromosome analysis of tumour cells in the bone marrow of a 13.5-year-old girl (without a primary tumour) revealed a pseudo-diploid or pseudo-tetraploid karyotype with a translocation involving the long arms of chromosomes 2 and 13: t(2;13)(q37;q14). This finding enabled the diagnosis of a dissemina
The cyclin-D1/PRAD1 oncogene, a key regulator of the G 1 -phase progression of the cell cycle, has been identified as the long-sought BCL-1 oncogene in B-cell malignancies with t(11;14)(q13;q32) translocation. A novel alternative spliced cyclin-D1 transcript, called transcript[b], has been identifie
The recurrent t(14;19)(q32;q13) translocation associated with chronic B-cell lymphoproliferative disorders, such as atypical chronic lymphocytic leukemia, results in the juxtaposition of the IGH@ and BCL3 genes and subsequent overexpression of BCL3. We report six patients with B-cell precursor acute
