摘要

Member RAS oncogene family (RAB1A), a member of the RAS oncogene family, cycles between inactive GDP-bound and active GTP-bound forms regulating vesicle transport in exocytosis. Thus, functional alterations of the RAB1A gene may contribute to aspirin intolerance in asthmatic sufferers. To investigate the relationship between single-nucleotide polymorphisms (SNPs) in the RAB1A gene and aspirin-exacerbated respiratory disease (AERD), asthmatics (n=1197) were categorized into AERD and aspirin-tolerant asthma (ATA). All subjects were diagnosed as asthma on the basis of the Global Initiative for Asthma (GINA) guidelines. AERD was defined as asthmatics showing 15% or greater decreases in forced expiratory volume in one second (FEV1) or naso-ocular reactions by the oral acetyl salicylic acid (ASA) challenge (OAC) test. In total, eight SNPs were genotyped. Logistic regression analysis identified that the minor allele frequency of +14444 T%26gt;G and +41170 C%26gt;G was significantly higher in the AERD group (n=181) than in the ATA group (n=1016) (p=0.0003-0.03). Linear regression analysis revealed a strong association between the SNPs and the aspirin-induced decrease in FEV1 (p=0.0004-0.004). The RAB1A gene may play a role in the development of AERD in asthmatics and the genetic polymorphisms of the gene have the potential to be used as an indicator of this disease.
