摘要

The gene, CRTH2, encoding a receptor for prostaglandin D2 (PGD2), is located within the peak linkage region for asthma on chromosome (Chr) 11q reported in African American families. Family-based analysis of asthma and two common SNPs [G1544C and G1651A (rs545659)] in the 3′-untranslated region of CRTH2 showed significant evidence of linkage in the presence of disequilibrium for the 1651G allele (P = 0.003) of SNP rs545659. Haplotype analysis yielded additional evidence of linkage disequilibrium for the 1544G-1651G haplotype (P < 0.001). Population-based case-control analyses were conducted in two independent populations, and demonstrated significant association of the 1544G-1651G haplotype with asthma in an African American population (P = 0.004), and in a population of Chinese children (P < 0.001). Moreover, in the Chinese children the frequency of the 1651G allele in near-fatal asthmatics was significantly higher than mild-to-moderate asthmatics (P = 0.001) and normal controls (P < 0.001). The 1651G allele of SNP re545659 was also associated with a higher degree of bronchial hyperresponsiveness (P < 0.027). Transcriptional pulsing experiments showed that the 1544G-1651G haplotype confers a significantly higher level of reporter mRNA stability, when compared with a non-transmitted haplotype (1544C-1651A), suggesting that the CRTH2 gene on Chr. 11q is a strong candidate gene for asthma.
