The 5' flanking region of the BCL2 gene (5'-BCL2) is a breakpoint cluster of
rearrangements with immunoglobulin genes (IGs). In contrast to t(14;18)(q32;q21)
affecting the 3' region of BCL2, 5'-BCL2 can fuse to not only the heavy chain
gene (IGH), but also two light chain gene (IGL) loci. We report here cloning and
sequencing of a total of eleven 5'-BCL2 / IGs junctional areas of B-cell tumors,
which were amplified by long-distance polymerase chain reaction-based assays. The
breakpoints on 5'-BCL2 were distributed from 378 to 2312 bp upstream of the
translational initiation site and, reflecting the alteration of regulatory
sequences of BCL2, 5'-BCL2 / IGs-positive cells showed markedly higher levels of
BCL2 expression than those of t(14;18)-positive cells. In contrast, the
breakpoints on the IGs were variable. Two 5'-BCL2 / IGH and two 5'-BCL2 /
IGLkappa junctions occurred 5' of the joining (J) segments, suggesting operation
of an erroneous variable (V) / diversity (D) / J and V / J rearrangement
mechanism. However, two other 5'-BCL2 / IGH junctions affected switch regions,
and the kappa-deleting element, which is located 24 kb downstream of the constant
region of IGLkappa, followed the 5'-BCL2 in another case. One 5'-BCL2 / IGLkappa
and two 5'-BCL2 / IGLlambda junctions involved intronic regions where the normal
recombination process does not occur. In the remaining one case, the 5'-BCL2
fused 3' of a Vlambda gene that was upstream of another Vlambda / Jlambda complex
carrying a non-producing configuration, indicating that the receptor editing
mechanism was likely involved in this rearrangement. Our study revealed
heterogeneous anatomy of the 5'-BCL2 / IGs fusion gene leading to transcriptional
activation of BCL2, and suggested that the mechanisms underlying the formation of
this particular oncogene / IGs recombination are not identical to those of
t(14;18).
