- Abstract
- Nasal polyps are abnormal lesions arising mainly from the nasal mucosa and paranasal sinuses. Since the human class II, major histocompatibility complex, transactivator (CHTA) is a positive regulator of class II, major histocompatibility complex gene transcription, the CHTA gene is thought to be involved in the presence of nasal polyps in asthma and aspirin hypersensitive patients. To investigate the association between CIITA and nasal polyposis, 18 single nucleotide polymorphisms (SNPs) were genotyped in 467 asthmatics who were classified into 158 aspirin-exacerbated respiratory disease (AERD) and 309 aspirin-tolerant asthma (ATA) subgroups. Differences in the frequency distribution of CH TA variations between polyp-positive cases and polyp-negative controls were determined using logistic analyses. Initially, a total of 9 CHTA variants were significantly associated with the presence of nasal polyps in the overall asthma, AERD and ATA groups [P=0.001-0.05, odds ratio (OR)=0.53-2.35 in the overall asthma group; P=0.01-0.02, OR=2.45-2.66 in the AERD group; P=0.001-0.05, OR=0.45-2.61 in the ATA group using various modes of genetic inheritance]. One the variations (rs12932187) retained this association after multiple testing corrections (P-corr=0.01) in the overall asthma group. In addition, two variations (rs12932187 and rs11074938) were associated with the presence of nasal polyps following multiple testing corrections (P-corr=0.02 and 0.04, respectively) in the ATA group. These novel findings suggest that rs12932187 and rs11074938 may constitute susceptibility markers of inflammation of the nasal passages in asthma patients.
