Three cellular or putative oncogenes: c-myc, bcl1, and bcl2 were previously found to be rearranged in some B cell malignancies due to chromosomal translocations. Data concerning the role of such genetic rearrangements in B-CLL are very scanty and limited to few cases in which bcl1 rearrangements were found. We studied DNA samples from 38 cases of B-CLL by Southern blot technique in order to find out the existence and frequency of such events. No bcl1 or bcl2 rearrangements were found in any of the studied cases; thus, involvement of these genes in CLL must be rare. In one patient who had an aggressive and resistant disease, c-myc rearrangement was found.
