Background
Nasal polyps are abnormal lesions that cause airway obstruction and can occur along with other respiratory diseases. On account of its association with aspirin exacerbated respiratory disease (AERD), the human discoidin, CUB and LCCL domain containing 2 (DCBLD2) is hypothesized to be a candidate gene for the development of nasal polyps in asthma patients.
Methods
A total of 12 single-nucleotide polymorphisms (SNPs) were genotyped in 467 Korean asthma patients who were stratified further into 108 AERD and 353 aspirin-tolerant asthma (ATA) subgroups. Five major haplotypes were inferred from pairwise comparison of the polymorphisms. The patients were matched to control for confounds, and differences in the frequency distribution of DCBLD2 SNPs and haplotypes were analyzed using logistic models via various modes of genetic inheritance.
Results
Results reveal significant association of rs828618 and DCBLD2_ht1 with nasal polyposis in the overall asthma patients group (P = 0.006, P corr = 0.05). Interestingly, the strength of association were maintained in the ATA subgroup (P = 0.007, P corr = 0.06), and moderate correlation was detected in the AERD subgroup (P = 0.04–0.05, P corr > 0.05).
Conclusions
Although further replication and validation are needed, these findings suggest that DCBLD2 could be a potential marker and drug target for treatment of nasal polyposis in Korean asthma patients.
