HLA-DR antigens and properdin factor B allotypes in responders and non-responders to the Rhesus-D antigen.
HLA-DRw6 incidence was high in male responders to the Rhesus-D antigen (50%) compared to male non-responders (15.4%), P less than 0.02, P corrected N/S, pregnancy immunized females (23.1%) and a random population (26%). No Bf allotype frequency differences were found among these four groups.
