Kim YC, Won SY, Jeong BH. The first association study of single-nucleotide polymorphisms (SNPs) of the IFITM1 gene with influenza H1N1 2009 pandemic virus infection. Mol Cell Toxicol. 2021 Feb 15:1-8
Background: The interferon-induced transmembrane (IFITM) protein family consists of interferon-stimulated genes (ISGs) that show potent antiviral capacity against a broad range of viruses. Many studies have been performed to investigate an association between IFITM3 polymorphisms and pandemic influenza A 2009 H1N1 virus infection. However, an association study of IFITM1 polymorphisms with susceptibility to this infection has not been reported thus far.
Objective: To identify an association between the susceptibility to pandemic influenza A 2009 H1N1 virus infection and IFITM1 polymorphisms, we compared genotype, allele and haplotype frequencies of the IFITM1 gene between healthy controls and pandemic influenza A 2009 H1N1-infected patients. In addition, we investigated linkage disequilibrium (LD) by Haploview 4.2 and the binding ability of transcription factors according to IFITM1 polymorphism alleles by PROMO. Furthermore, we measured the LD value between the IFITM1 gene and the IFITM3 gene.
Results: We found 3 novel single-nucleotide polymorphisms (SNPs) and did not find an association between IFITM1 SNPs and susceptibility to pandemic influenza A 2009 H1N1 virus infection. We found strong LD among IFITM1 SNPs but did not find a difference in the transcription factor-binding ability according to regulatory IFITM1 SNP alleles. In addition, we found strong LD between IFITM1 SNPs and IFITM3 SNPs.
Conclusion: To the best of our knowledge, this report is the first association study of the susceptibility to pandemic influenza A 2009 H1N1 virus infection and IFITM1 polymorphisms.
