As for the EBV associated serostatus, EBV-VCA-IgG (Figure 3F), high avidity EBV-VCA-IgG (Figure 3G) and EBNA-IgG (Figure 3J) were present in patient's serum, while EBV-VCA-IgM (Figure 3H) and EBV-EA-IgG (Figure 3I) were absent, suggesting a chronic EBV infection without relapse or reactivation. The gene discussed is CD40LG; the disease is Epstein-Barr virus infection.
