IFNAR2 and pneumonia: When we examined 13 loci associated with COVID-19 [35] and susceptibility to pneumonia in our cohort we found an association between the C allele of rs13050728 in IFNAR2 (Interferon Alpha and Beta Receptor Subunit 2) gene and lower risk of developing pneumonia (OR 0.94, 95%CI [0.90–0.98], p = 0.0028, Table 5), an observation directionally similar to that for severity of COVID-19 [35].
