We also considered 10 loci mutated in patients with other viral illnesses but directly connected to the three core genes conferring influenza susceptibility: TICAM1/TRIF (9), UNC93B1 (10), TRAF3 (11), TBK1 (12), IRF3 (13), and NEMO/IKBKG (14) in the TLR3-dependent type I IFN induction pathway, and IFNAR1 (15), IFNAR2 (16), STAT1 (17), and STAT2 (18) in the IRF7- and IRF9-dependent type I IFN amplification pathway. Here, TRAF3 is linked to influenza.
