Researchers have created the first evolutionary history of the duplications in the human genome that are partly responsible for both disease and recent genetic innovations. This work marks a significant step toward a better understanding of what genomic changes paved the way for modern humans, when these duplications occurred and what the associated costs are - in terms of susceptibility to disease-causing genetic mutations.

UCLA scientists design masks to hide genetic mutations from cell

UCLA scientists have devised a novel way to correct abnormal gene splicing-a common mutation that often leads to disease. Splicing edits out the punctuation from a cell's genetic blueprint, enabling its code to dictate protein production by the cell. Using new technology made by Gene Tools of Oregon, the researchers designed a custom mask to camouflage each abnormal splice. The technique prevents the cell from seeing the genetic defects and restores splicing to the correct location in the gene.
