Association of ANRIL Gene Single-Nucleotide Polymorphisms With Allergic Rhinitis in Kurdish Population From Kermanshah, Iran.

Abstract

Background: Allergic rhinitis (AR) is the most common inflammatory disorder of the upper airway caused by aberrant immune responses to allergens in genetically predisposed individuals. Recently, the long noncoding RNA (lncRNA) antisense noncoding RNA in the INK4 locus (ANRIL) has been identified as a novel genetic factor associated with increased AR risk.

Objectives: This study aimed to evaluate the potential correlation of ANRIL gene single nucleotide polymorphisms (SNPs) with AR risk in the Kurdish population of Kermanshah, Iran.

Methods: In this case-control study, 130 AR patients and 130 healthy controls were recruited to genotype for two SNPs of the ANRIL gene (rs1333048 and rs10757278) using the Tetra-primer amplification refractory mutation system polymerase chain reaction (T-ARMS-PCR) method.

Results: Our results showed no significant difference for the alleles and genotypes frequency distribution of lncRNA ANRIL SNPs (rs1333048 and rs10757278) between AR patients and healthy controls (p > 0.05). Additionally, the dominant, additive and recessive genetic models of both SNPs were not associated with altered susceptibility to AR risk (p > 0.05).

Conclusion: The results demonstrated that the ANRIL gene rs1333048 and rs10757278 polymorphisms might not be associated with susceptibility to AR in the Kurdish population of Kermanshah, Iran.
