Abstract
BACKGROUND:: OBJECTIVE:: METHODS:: RESULTS:: The microsatellite analyses provided tentative support for an asthma/lung function susceptibility locus (48.9-49.1Mbps), and fine mapping localized modest association to the PLAUR gene. PLAUR SNPs in the 5′ region, intron 3, and 3′ region are associated with asthma and BHR susceptibility and predict FEV1 and plasma PLAUR levels. SNPs in the 5′ region showed association for asthma (2 populations), FEV1 (2 populations), and BHR (2 populations) phenotypes. SNPs in intron 3 showed association with asthma (2 populations) and BHR (3 populations). Importantly, the same 5′ region and intron 3 SNPs were associated with plasma PLAUR levels. The same 5′ region and 3′ region SNPs were found to be determinants of FEV1 decline in subjects with asthma. CONCLUSION:: This study represents the first report to identify PLAUR as a potential asthma susceptibility gene and determine PLAUR regions underlying this association, including a role in influencing plasma PLAUR levels. Finally, the association of PLAUR with lung function decline supports a role for PLAUR in airway remodeling in asthma.
