STING1 and legionellosis: The frequency of HAQ TMEM173/STING (but not R232H TMEM173/STING) was significantly increased among cases (0.18) as compared to controls (0.075) (Table 1); an unadjusted analysis showed that carriage of the haplotype almost tripled the odds of being a legionellosis patient in this cohort (p = 0.028; OR 2.69; 95%CI, 1.16–6.27).
