A de novo direct duplication of 9p22βp24 was shown in a child with a duplication 9p phenotype by GTG banding and fluorescence in situ hybridization (FISH) using a chromosome-9 specific painting probe as well as 6 YAC DNA probes localized to the 9p13-9p23 region. The breakpoints in this patient and p

Authors report on a case of partial 9p duplication, involving the 9p22-9p24 region. This represents the second case of such duplication in which the breakpoints were precisely defined using fluorescence in situ hybridisation (FISH) with chromosome 9 specific painting and YAC DNA probes, localised on
A 3-year-old girl with duplication 9 (p22 leads to p13) is reported. The presence of a classical 9p trisomy phenotype in this patient suggests that this region (or part of it) is responsible for the major, typical clinical stigmata of this partial autosomal trisomy syndrome.
