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.

UI MeSH Term Description Entries
D008677 Metaphase The phase of cell nucleus division following PROMETAPHASE, in which the CHROMOSOMES line up across the equatorial plane of the SPINDLE APPARATUS prior to separation.
D002877 Chromosomes, Human Very long DNA molecules and associated proteins, HISTONES, and non-histone chromosomal proteins (CHROMOSOMAL PROTEINS, NON-HISTONE). Normally 46 chromosomes, including two sex chromosomes are found in the nucleus of human cells. They carry the hereditary information of the individual. Chromosome, Human,Human Chromosome,Human Chromosomes
D005819 Genetic Markers A phenotypically recognizable genetic trait which can be used to identify a genetic locus, a linkage group, or a recombination event. Chromosome Markers,DNA Markers,Markers, DNA,Markers, Genetic,Genetic Marker,Marker, Genetic,Chromosome Marker,DNA Marker,Marker, Chromosome,Marker, DNA,Markers, Chromosome

D014178 Translocation, Genetic A type of chromosome aberration characterized by CHROMOSOME BREAKAGE and transfer of the broken-off portion to another location, often to a different chromosome. Chromosomal Translocation,Translocation, Chromosomal,Chromosomal Translocations,Genetic Translocation,Genetic Translocations,Translocations, Chromosomal,Translocations, Genetic

D020161 Physical Chromosome Mapping Mapping of the linear order of genes on a chromosome with units indicating their distances by using methods other than genetic recombination. These methods include nucleotide sequencing, overlapping deletions in polytene chromosomes, and electron micrography of heteroduplex DNA.

D020223 Chromosome Painting A technique for visualizing CHROMOSOME ABERRATIONS using fluorescently labeled DNA probes which are hybridized to chromosomal DNA. Multiple fluorochromes may be attached to the probes. Upon hybridization, this produces a multicolored, or painted, effect with a unique color at each site of hybridization. This technique may also be used to identify cross-species homology by labeling probes from one species for hybridization with chromosomes from another species.
