Chromosome fusion in humans

WebJul 31, 2015 · In 1991, scientists reported finding alleged evidence of a telomere-telomere fusion event on human chromosome 2, but it was not quite what they were expecting. 3 First, the sequence was only about 800 bases long—not the 10,000 bases or more you would expect if two 5,000-base (or larger) telomeres fused together. 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. The identification of these fusion genes play a prominent role in being a diagnostic and prognostic marker.
