Hybrid interval map and framework map summary. A G-banded representation of Xq22.3–q26.3. The deletion-hybrid breakpoints define nine intervals (A–I) into which the 69 STSs have been placed. Within deletion intervals, STSs and their associated loci are shown in the order in which they appear on the framework map. The approximate positions and extents of the four YAC contigs are indicated by numbered bars. Numbers within the arcs at left of the contigs indicate the number of separate FISH experiments, using different PAC probe combinations, that support the contig order (arc drawn between bars) or orientation (within bars).
