Figure 2 The frequent karyotype abnormalities in CLL are not mutually exclusive. Representative G-banded karyotype of a CLL showing deletions of the long arm of chromosome 11 as well as of chromosome 13: 46,XX,del(11)(q21),del(13)(q14).

Figure 3 Deletions of chromosome 13 are the most frequent karyotype alterations in CLL. (A, left to right): Ideogram of chromosome 13, example of an interstitial deletion of the long arm of chromosome 13 in CLL, and example of a terminal deletion of chromosome 13 in CLL. (B) Part of a metaphase with monoallelic deletion of chromosome 13 as detected by FISH, the orange (spectrum: orange)-labeled probe detects the minimal deleted region, the green (spectrum: green)-labeled probe detects a terminal DNA segment of the long arm of chromosome 13 to facilitate its identification. Chromosomes are counterstained by DAPI. (C) Part of a metaphase with diallelic deletion of chromosome 13 as detected by FISH. For probes and counterstaining see (B). (D, left to right): nucleus of a normal cell without 13q-deletion and nucleus of a cell with biallelic deletion. For probes and counterstaining see (B).
