In addition to confirming the previously identified asthma gene located on chromosome 17, researchers found another gene located on chromosome 1q31 was associated with an increased risk of childhood asthma in both children of European and African ancestry.
Asthma (AZ-ma) is a chronic (long-term) lung disease that inflames and narrows the airways. Asthma causes recurring periods of wheezing (a whistling sound when you breathe), chest tightness, shortness of breath, and coughing. The coughing often occurs at night or early in the morning. Asthma affects people of all ages, but it most often starts during childhood. In the United States, more than 25 million people are known to have asthma. About 7 million of these people are children.
