Bridging the gap in research is particularly important for diseases that affect African Americans more than the rest of the population.

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?
