A. Sequences of PCR products from junctions aligned to reference human genome sequence. Upper case, chromosome 10 sequences. Lower case, chromosome 7 sequences. Upper case italics, origin unknown. B. UCSC Genome Browser tracks showing genes flanking the translocation breakpoints (arrows) and BAC clones used for FISH. C. FISH showing three signals for chromosome 7 (left) and chromosome 10 (right) BAC probes shown in B. D. Cartoon illustrating orientation of flanking genes and relative distances from translocation breakpoints.
