In 2007, researchers were dazzled by the degree to which genomes differ from one human to another and began to understand the role of these variations in disease and personal traits. Science and its publisher, AAAS, the nonprofit science society, recognize "Human Genetic Variation" as the Breakthrough of the Year, and identify nine other of the year's most significant scientific accomplishments.

Genome rearrangements, resulting in variations in the numbers of copies of genes, occur when the cellular process that copies DNA during cell division stalls and then switches to a different genetic "template," said researchers at Baylor College of Medicine in Houston in a report that appears today in the journal Cell.

 | Researchers offer a new view of what causes the greatest genetic variability among individuals - suggesting that it is due less to single point mutations than to the presence of structural changes that cause extended segments of the human genome to be missing, rearranged or present in extra copies. ...> Full Article |
Today, researchers from the University of Colorado at Denver and Health Sciences Center (UCDHSC), along with colleagues from Stanford University, report the results of a large-scale, genome-wide study to investigate gene copy number differences among ten primate species, including humans.
