Abstract

A genetic association study was performed with coding variants of Fc epsilon RI beta in relation to atopic and non-atopic asthma in a Japanese population (n = 400). A coding variant of Gly237Glu in exon 7 of Fc epsilon RI beta gene showed association with atopic asthma (OR = 3.00, chi 2 = 5.10, p < 0.03), but not with non-atopic asthma; this was seen particularly in childhood asthma (OR = 3.92, chi 2 = 8.66, p < 0.005). This variant is also associated with very high total serum IgE levels (> mean + 3 SD, OR = 8.56, chi 2 = 46.2, p < 0.0001), but not any allergen specific IgE. However, Leu181lle, another variant of Fc epsilon RI beta related to atopy in British and Australian populations, was not found in this Japanese population. These results suggest that variants of Fc epsilon RI beta may be an important genetic cause of the atopic asthma.
