While the proportions of FcRγneg EAT-2neg SYKneg NK cells vary among individuals and at different time points, the percentage of NK cells expressing other receptors associated with CMV infection, including CD57 (range 10–54%) or NKG2A (range 20–84%), exhibited little variation across time (Figure 6A). The gene discussed is B3GAT1; the disease is cytomegalovirus infection.
