Figure 2 Direct labelled FISH probes were designed to span and flank the NFI gene region. The probe schematic demonstrates the 12 BAC/PAC probes that were deleted, indicated by the dashed lines. The BACs represented with a solid line indicate the probes that were present. The total size of the deletion was determined to be 1.94 Mb. Genes located at the deletion end points are also indicated on the schematic.
