Figure 5.

Location, on the chromosome 7q physical map, of the breakpoint region in patient FB336R. The breakpoint region in patient FB336R, detected by probe 6a8f, is indicated by a dotted bar. The breakpoint lies ⩾500 kb distal to fragile-site region FRA7H, which is indicated by a hatched bar. Unblackened bars denote groups of markers for which the local order has not been determined; blackened circles, genetic markers; blackened squares or bars, ESTs or genes. Other markers shown are STSs or unique DNA probes.
