 | | Although the exact genes controlling susceptibility to asthma have not been identified, several genome-wide searches have provided evidence for the linkage of asthma or asthma-related traits (serum IgE levels, skin test reactivity, bronchial hyper-responsiveness, blood eosinophils) to loci on multiple autosomal chromosomes [1,2,3,4,5,6]. |
 | | Of particular interest is the 5q31-33 region, which contains the T helper type 2 (Th2) cytokine gene cluster [interleukin (IL)-4, IL-13, IL-5 and IL-9] and has been linked to asthma or related phenotypes in many studies [2,3,4,5,6,7,8]. |
 | | To test for a genetic association with clinical asthma and IgE they conducted case control studies in a British population (150 young adults with asthma and atopy, and 150 controls) and a Japanese population (100 young adults with asthma and atopy, 100 subjects with non-atopic asthma, and 100 controls). |
