Researchers Find Genetic Clues To Intestinal Disease
In a series of recently published studies, Johns Hopkins researchers have shown that an intestinal disease affecting 400,000 people in the United States is actually a variety of related disorders that can be inherited and cause similar symptoms in close relatives.
