We next investigated the nature of the sequence underlying the pericentric inversion breakpoint by extracting the 1 Mb interval encompassing the sequence between the most distal PTR XVp probe, RP11-360J18, and the most proximal PTR XVq probe, RP11-736I24, from the November 2002 human genome assembly.
All probes tested between RP11-360J18 and RP11-736I24 produced signals on PTR XVp and PTR XVq near the centromere.
On the basis of the appearance of dual FISH signals on PTR XVp and XVq, the general location of the pericentric inversion breakpoint was identified with probe RP11-40J8 (Figures 1, 3).
This interval includes approximately 600 kb of sequence spanning FISH probes RP11-932O9, RP11-605N15, RP11-422F16, RP11-40J8 and RP11-382B18, all of which produced dual FISH signals flanking the centromere in PTR XVq and XVp (Figures 3, 4).
3 CHRNA7 locus, produced a single FISH signal on PTR XVq only (summarized in Figure 1).
