Two cases of amplified repetitive elements accidentally identified in cancer samples are reported. In both cases, repeated DNA that is normally not visible by traditional chromosome banding had increased in amount to become cytogenetically visible. In one case, an addition to the short arm of chromosome 1 was originally diagnosed. However, upon molecular analysis the diagnosis could be corrected to an amplification of the D1Z2 repeat. In the second case, a strongly DAPI-positive band was visible at the top of the short arm of chromosome 22, and the original diagnosis was add(22). Staining for telomeric repeats revealed their presence inside the DAPI-positive element, thus confirming that the element in question was truly added to the end of the chromosome. Curiously, no telomeric repeats could be detected distal to the DAPI-positive element. The identity of the DAPI-positive element could not be established, as it was not stained by any of the specific probes applied, nor in a scanning hybridization with labeled Cot-1 DNA. It thus seems to represent an expansion from some lowly repetitive AT-rich DNA translocated to the tip of chromosome 22.
