Probes and methods of using the probes to detect chromosomal rearrangements and/or deletions are provided. The methods utilize probes that are free of repeat sequences to provide greater selectivity and sensitivity; methods for producing such probes are also disclosed. The probe sets utilized in the detection methods are designed to hybridize to chromosomes at regions outside known breakpoints, instead of spanning the breakpoint as with conventional FISH methods, and, in some instances, are further designed to bind to regions located outside the genes involved in the rearrangement. Methods utilizing probe sets with two and four colors are also described, as are automated methods for analyzing rearrangements.
