HLA-DRB1 and infection: Interestingly, three alleles were related to more than one event; DRB1*08:02:01G and DRB1*12:01:01G had concordant effects (GP for persistence and EO for redetection and LO for infection and GP for clearance) while DRB1*14:02:01G had an opposite effect (LO for infection and GP for persistence) (Table 2).
