In contrast, IFNγ in this anaphylaxis patient (32.9 ± 0.3 pg/ml) was 11–16 fold lower than the average of all d90 patients, AR average and non-AR group average (474.7 ± 169.1, 365.9 ± 139.8, and 534.6 ± 251.5, respectively, Figure 1B; Table S2 in Supplementary Material), though 9 other AR patients and 14 non-AR patients had even lower IFNγ levels. Here, IFNG is linked to anaphylaxis.
