which chromosome is asthma located on
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.
The regions on chromosomes 7 and 12 may coincide with the asthma and atopy loci on the same chromosomes. Polymorphism in the IL1 cluster on chromosome 2 has also been shown to influence the severity of the disease (95, 96).
