Partial deletion of the long arm of chromosome 5: A fluorescence in situ hybridization study using band-specific painting probes generated by chromosome microdissection

A series of 17 patients with myeloid disorders and partial deletions of the long arm of chromosome 5 were investigated using fluorescence in situ hybridization with 5q34-q35 region-specific painting probes generated by chromosome microdissection. This approach confirmed that partial 5q deletions are interstitial in all the cases studied. In addition no translocation involving chromosome 5 was detected.
