Fish testing chromosomal translocations

Websitu hybridization (FISH) techniques, using chromosome-specific DNA libraries. Stable aberrations (translocations) were detected using two cocktails of DNA libraries specific for three chromosomes, namely 1, 3 and X and 2, 4 and 8, representing ~40% of the whole human genome. The frequencies of dicentrics and translocations increased in a Because a FISH test can detect genetic abnormalities associated with cancer, it's useful for diagnosing some types of the disease.
