December 6, 2012 Researchers found a surprising number of mutations, including several associated with disease, in the genes of normal healthy people. Their study raises questions about whether widespread genetic sequencing could end up scaring people for no good reason.
October 24, 2012 Scientists have made changes in human DNA that can be passed down from one generation to the next. The researchers say they took the step to try to prevent women from giving birth to babies with genetic diseases. But the research is raising a host of social and moral questions.
September 25, 2012 Doctors used genome sequencing to put a name to the mysterious cluster of symptoms that afflicted Christian Terry, 5. He's one of many patients now getting the test, which can cost as little as $1,000, to resolve undiagnosed illnesses. Doctors are also using it to sequence cancer and target treatment at the precise genetic mutations in a tumor.
September 20, 2012 Different lineages of cat with the same coloration got their looks in unique ways. The genetic variants that determine those patterns come from different mutations in the same genes. And that has some scientists thinking there may be more to the genes than meets the eye.
