As shown in Figure 2A, 30.2% of all patients with an asymptomatic EBV-infection encoded for the low-expressing HLA-E*0101/0101 variant, while 43.8% and 26% encoded for the heterozygous HLA-E*0101/0103 and the high-expressing HLA-E*0103/0103 allele, respectively. Here, HLA-E is linked to Epstein-Barr virus infection.
