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.
Whether the association between the 15q24 susceptibility locus and lung cancer is direct (i.e., there is a gene in that region that causes lung cancer) or indirect (i.e., there is a gene in that region that causes tobacco addiction, which in turn causes lung cancer) remains to be determined.
