Fusion gene

In genetics, a fusion gene is a hybrid gene formed from two previously independent genes. It can occur as a result of translocation, interstitial deletion, or chromosomal inversion. Fusion genes have been found to be prevalent in all main types of human neoplasia.[1] The identification of these fusion genes play a prominent role in being a diagnostic and prognostic marker.[2]
