Summary of the physical map in 8p11 encompassing the 8; 13 translocation breakpoint.The position of genetic markers from the physical map relative to the chromosome 8 centromere (cen) and telomere of the short arm (pter) are shown at the top. The presence of these markers (indicated by the vertical lines) in a series of YACs (indicated by the horizontal bars) is shown. Since there are no markers linking YACs 782H11 and 910D7, the distance between the ends of these YACs could not be determined. The 8; 13 translocation breakpoint lies in the interval between the ends of YACs 676A7 and 782H11.
