Notably, neutrophil elastase (ELANE), a neutrophil degranulation factor66 as well as a component of neutrophil extracellular traps (NETs)67, was elevated in both pregnant and non-pregnant COVID-19 cases (Fig. 6f), as was histone H3.1 (H3C1), another NET component (Fig. 6g). The gene discussed is ELANE; the disease is COVID-19.
