Abstract: Microdissection and fluorescence in situ hybridisation (FISH) were used to elucidate the nature of a complex chromosome translocation, after GTG banding failed in the complete characterisation of the structural rearrangement between chromosomes 6 and 12. These chromosomes were painted with chromosome specific paints and one of the chromosome regions involved in the translocation was isolated by microdissection. Ten copies of the microdissected region were collected with microneedles from GTG banded metaphases, transferred to a collecting drop, and amplified by means of DOP-PCR. The PCR product was labelled with biotin-14-dATP and used as a FISH probe for hybridisation to normal metaphase chromosomes and metaphase chromosomes of the patients (microFISH). FISH with this chromosome region specific painting probe and with chromosome band specific probes enabled the characterisation of a complex chromosome rearrangement with five breakpoints in two chromosomes. This resulted in the following karyotype: 46,XY,t(6;12)(6pter--> 6q12::12q24.1-->12qter;12qter-->12q13.3:: 6q16.2-->6q26::12q13.3-->12q24.1::6q12--> 6q16.2::6q26-->6qter).
