Did You Know? One in Twelve African Americans has Sickle Cell Trait

February 14, 2012
In the United States alone, about 100,000 people have sickle cell disease and roughly one in 500 black or African-American babies is born with it. The genetic mutation underlying this condition causes red blood cells to take on a "sickle" shape, which makes it harder to deliver oxygen to certain parts of the body. But why would a mutation that causes a harmful disease survive through evolution to the high frequency with which we observe it today?

SNPwatch: Eating Veggies Can Decrease Genetic Risk for Heart Attack

November 22, 2011
For some, eating a doughnut every morning is a recipe for heart attack. Certain genetic factors are also associated with developing cardiovascular disease. But lifestyle choices can impact the effect of genetics on risk. A new study suggests that eating a prudent diet -- high in raw fruits and vegetables -- can counteract the effect of one of the most well-established genetic risk factors for coronary heart disease.
