- Abstract
- The human HLA class II histocompatibility antigen, DR alpha chain (HLA-DRA) is a member of the MHC class II gene family that activates T cells allowing secretion in various cytokines to immune responses. Thus, we explored whether the genetic variations in HLA-DRA gene can influence susceptibility for aspirin exacerbated respiratory disease (AERD). To carry out the investigation, 22 single nucleotide polymorphisms (SNPs) in HLA-DRA were genotyped in 592 Korean asthma patients. Logistic and regression analyseis wereas used to evaluate the P-values for associations of HLA-DRA polymorphisms with AERD and a relevant phenotype, the fall rate of forced expiratory volume in the 1(st) second (FEV1). Logistic analyses revealed that two variants, rs6911777 and HLA_DRA_BL1_ht3 were initially associated with AERD via dominant and recessive models (P = 0.05 and 0.01, respectively), however, the signals did not reach the threshold of significance after multiple corrections. Furthermore, we observed that fall rate of FEV1 by aspirin provocation was marginally different between AERD cases and aspirin-tolerant asthma (ATA) controls (mean = 24.63 vs 3.54, respectively). This study provides result of first association analysis between the variants of HLA-DRA and the risk of AERD, and conclusions derived from the study do not support significant roles of polymorphisms in HLA-DRA with AERD.
