The beta subunit of high affinity immunoglobulin E (IgE) receptor (FcepsilonRIbeta) and the Clara cell derived inflammatory molecule, CC16 have been cited as candidate genes for atopic asthma on chromosome 11q13. A genetic association study was performed with an intragenic microsatellite repeat of CC16 gene on chromosome 11q12-13 in relation to atopic and non-atopic asthma. Whereas variants of FcepsilonRIbeta at chromosome 11q13 show association with atopy and asthma, no significant association was found between asthma and CC16 genotypes irrespective of atopic status. These data support the candidacy of FcepsilonRIbeta rather than CC16 for the atopic asthma locus on chromosome 11q.
