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 outsid e known breakpoints, instead of spanning the breakpoint as with conventional FISH methods, and, in some instances, are further designed to bind to region s 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.
