Chromosome 17 (patient 1 and 2) and chromosome 21 (patient 1) array CGH profiles. On the x-axis, clones are ordered by Mb position on chromosome 17 and 21, respectively, and on the y-axis log2T/R ratios are shown. Hidden Markov Model was used to identify the duplications (green lines) and deletions (red lines) in patient 1 and 2. a In patient 1, chromosome 17 shows two interspersed deletions of ∼600 kb (17p13.3–Del I) and ∼2.2 Mb (17p12–Del II), respectively, and a duplication of ∼6.1 Mb (Dup I). b Additionally, a 4.4 Mb duplication of 21q22.3 was observed (Dup II). c Patient 2 showed four interspersed duplications on 17p11–p13 (Dup I–Dup IV), in total comprising ∼8.8 Mb of genomic sequence. All alterations were shown to be de novo

Ideograms and FISH results of patient 2. Schematic representation of the normal 17p and der(17). The locations of the FISH probes are shown on the left side of each figure panel. a The distal breakpoint of duplication I showed a relatively simple fluorescence signal pattern with probes RP11-810M2 (green; normal) and RP11-597I9 (red; duplicated). b The proximal breakpoint of duplication I showed a duplicated signal for RP11-222J21 (green) and a normal signal for RP11-98D15 (red). c Direct orientation of duplication III was shown using BAC clones RP11-601N13 (green) and RP11-726O12 (red). d For the distal breakpoint of duplication IV, BAC clones RP11-448D22 (green) and CTD-2145A24 (red) showed duplicated signals on der(17), indicating that both middle SMS-REP and LCR17pB are duplicated as a block. Four red signals on der(17) representing two normal and two duplicated copies of LCR17pA/B (dup III) and LCR17pB (dup IV) and four green signals depicting three normal copies of SMS-REPs and the duplicated middle SMS-REP. Summary of FISH results is provided in Table 2

Schematic representation of the proposed mechanism for CCR formation in patient 1 and patient 2. a The complex rearrangement observed in patient 1 includes nine breakpoints, with one insertion, two microdeletions and two microduplications. We propose that the breaks in chromosome 17, p13.3, p12 and p11.2 as well as the break in chromosome 21q22.3 arose simultaneously. This resulted in the insertion of the MDLS region into the middle SMS-REP/LCR17pB block, loss of telomeric 17p and part of 17p12 and duplication of the CMT1A region. Additionally, the duplicated 21q22.3 fragment was translocated to the 17p subtelomeric region. b The complex rearrangement in patient 2 included eight breaks. We suggest that breaks in chromosome 17, p13.2, p13.1, p12 and p11.2 occurred at the same time, resulting in four interspersed directly orientated microduplications. Arrows do not represent a chronological order of events

Schematic diagram of breakpoints for DNA rearrangements in 17p. Top: Cytogenetic chromosome bands 17p12, and sub-bands 17p11.2 and 17p11.1 are shown. Breakpoints of the chromosome rearrangements in patients 1 and 2 associated with architectural features in proximal 17p are shown by vertical dotted blue arrows. In patient 1, one breakpoint is located within the middle SMS-REP/LCR17pB block, whereas in patient 2 breakpoints are located within LCR17pA (proximal Dup III), middle SMS-REP (distal Dup IV) and LCR17pC (proximal Dup IV). Duplication III and IV in patient 2 are indicated by horizontal blue lines. Bottom: Previously identified rearrangements associated with LCRs in 17p. Breakpoints of translocations and isochromosome 17q are indicated by vertical black arrows whereas common ∼4 Mb and uncommon ∼5 Mb SMS deletions and marker chromosomes are indicated by black horizontal lines. The LCR17p structures are depicted in colors to better represent their positional orientation with respect to each other; the shaded rectangles and horizontal black arrows represent the orientation of the LCRs

Ideograms and FISH results of patient 1. Schematic representation of a normal 17p and der(17) (black and white) with translocated chromosome 21 material (blue). The location of the FISH probes are shown on the left side of each figure panel; der(17) is indicated on FISH pictures by a white arrow. a Terminal deletion of 17pter was validated using BAC clones RP11-1260E13 (red) and CTD-2326F1 (green) (del I). b FISH with PMP22-specific PAC RP1-150M12 (red) RA11-specific and BAC RP11-525O11 (green) revealed direct duplication of the CMT1A and SMS regions in 17p12p11.2 (dup I). c FISH with PAC RP1-95H6 (red; adapted from Chong et al. 1997) and BAC GS-202L17 (green; adapted from Knight et al. 2000) showed inverted insertion of the MDLS region into the SMS region. d Array CGH also identified a duplication of 21q22.3 (dup II). Additional FISH analysis using BAC clones RP11-40L10 (green) and RP11-16B19 (red) revealed that the duplicated material of 21q22.3 was translocated onto der(17). Summary of FISH results is provided in Table 1
