Abstract:
Molecular characterization of breakpoints of chromosomal rearrangements is a successful strategy for the identification of candidate disease genes. Mapping translocation breakpoints and rearranged chromosomal boundaries is labor intensive and/or time consuming. Here, we present a novel and rapid procedure to map such chromosomal breakpoints by hybridizing amplified microdissection derived DNA of aberrant chromosomes to arrays containing genomic clones. We illustrate the potential of the technique by molecularly delineating the breakpoints in five small supernumerary marker chromosomes (sSMC) and mapping the breakpoints of five different chromosomal translocations.

LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops resemble the...
