Rationale: Asthma is a common respiratory disease with complexgenetic components. We previously reported strong evidence forlinkage between mite-sensitive asthma and markers on chromosome5q33. This area of linkage includes a region homologous to amouse area that contains a locus involved in regulation of airwayhyperreactivity. Objective: The aim of the present study isto identify asthma susceptibility genes on chromosome 5q33.Methods and Results: We performed mutation screening and associationanalyses of genes in the 9.4-Mb human linkage region. Transmissiondisequilibrium test analysis of 105 polymorphisms in 155 familieswith asthma revealed that six polymorphisms in cytoplasmic fragileX mental retardation protein (FMRP)interacting protein2 gene were associated significantly with the development ofasthma (p = 0.000075; odds ratio, 5.9). These six polymorphismswere in complete linkage disequilibrium. In real-time quantitativepolymerase chain reaction analysis, subjects homozygous forthe haplotype overtransmitted to asthma-affected offspring showedsignificantly increased level of cytoplasmic FMRP interactingprotein 2 gene expression in lymphocytes compared with onesheterozygous for the haplotype (p = 0.038). Conclusions: Ourdata suggest that cytoplasmic FMRP interacting protein 2 areassociated with the development of atopic asthma in humans,and that targeting cytoplasmic FMRP interacting protein 2 couldbe a novel strategy for treating atopic asthma.
