Building on a tool that they developed in yeast four years ago, researchers at the Johns Hopkins University School of Medicine scanned the human genome and discovered what they believe is the reason people have such a variety of physical traits and disease risks.
In a report published in the June 25 issue of Cell, the team identified a near complete catalog of the DNA segments that copy themselves, move around in, and insert themselves here and there in our genome. The insertion locations of these moveable segments — transposons — in each individual’s genome helps determine why some are short or tall, blond or brunette, and more likely or less likely to have cancer or heart disease. The Johns Hopkins researchers say that tracking the locations of transposons in people with specific diseases might lead to the discovery of new disease genes or mutations.
