Chromosome fusion in humans
WebNov 14, 2007 · Humans normally have 46 chromosomes. However, sometimes two chromosomes will fuse together to form one big chromosome. Centric fusions are where two acrocentric chromosomes (chromosomes with the centromere very close to one end) fuse to make a large metacentric chromosome (one with the centromere near the middle). WebFusion genes are structural chromosomal rearrangements resulting in the exchange of DNA sequences between genes. This results in the formation of a new combined gene. They have been implicated in carcinogenesis in a number of different cancers, though they have been understudied in high grade serous ovarian cancer. This study used high throughput …
