    Abstract:
    BACKGROUND: Our previous work on linkage analysis showed that histamine release from basophils to anti-IgE stimuli was linked to the gene marker of chromosome 11q13, where the beta chain of the high-affinity receptor for IgE (FcepsilonRI-beta) is located. OBJECTIVE: To evaluate the association between FcepsilonRI-mediated histamine release from basophils and four bi-allelic single nucleotide polymorphisms of the FcepsilonRI-beta gene. METHODS: Phenotypes of asthma, such as maximal histamine release from basophils and atopy, were measured from 80 randomly recruited asthmatic children. Polymorphisms of the FcepsilonRI-beta gene were determined by PCR-based methods. RESULTS: The polymorphism in exon 7, resulting in Glu to Gly substitution, was significantly associated with histamine release from basophils to anti-IgE stimuli, but not with total IgE levels and skin test responses to aeroallergens. CONCLUSION: This study supports a role for the FcepsilonRI-beta gene in the expression of high affinity IgE receptor-mediated histamine release from basophils.
