In addition, the Korean population did not show association between the rs34481144 SNP and the susceptibility of 2009 pandemic H1N1 influenza A. The rs6598045 SNP, which is located on the proximal promoter of the IFITM3 gene, is related to transcriptional efficiency via the binding ability of the transcription factor TFII-I and is a novel candidate SNP associated with the susceptibility to 2009 pandemic H1N1 influenza A infection [11]. The gene discussed is IFITM3; the disease is influenza A (H1N1).
