Purpose: Aspirin exacerbated respiratory disease (AERD) results in a severe asthma attack after aspirin ingestion in asthmatics. The filamin A interactingprotein 1 (FILIP1) may play a crucial role in AERD pathogenesis by mediating T cell activation and membrane rearrangement. We investigatedthe association of FILIP1 variations with AERD and the fall rate of forced expiratory volume in one second (FEV1). Methods: A total of 34common FILIP1 single nucleotide polymorphisms (SNPs) were genotyped in 592 Korean asthmatic subjects that included 163 AERD patients and 429aspirin-tolerant asthma (ATA) controls. Results: This study found that 5 SNPs (P=0.006-0.01) and 2 haplotypes (P=0.01-0.03) of FILIP1 showednominal signals; however, corrections for the multiple testing revealed no significant associations with the development of AERD (Pcorr>0.05). In addition,association analysis of the genetic variants with the fall rate of FEV1, an important diagnostic marker of AERD, revealed no significant evidence(Pcorr>0.05). Conclusions: Although further replications and functional evaluations are needed, our preliminary findings suggest that geneticvariants of FILIP1 might be not associated with the onset of AERD.
