Red cells of propositus were agglutinated weakly by high titer anti-B human sera and anti-A+ B from group O sera. Her red cells reacted as strongly as group O cells with anti-H eel serum. Her serum contained an anti-B antibody which agglutinated normal B red cells at 4°C in saline but did not agglutinate her own red cells. Her saliva contained H substance in normal amoumt of group O secret or saliva. As the B substance did not detect in her saliva by inhibition test of anti-B agglutinin, she was termed blood group Bx analogous to those described for A<SUB>X</SUB>.<BR>Her father was group AB and his red cells reacted weakly with anti-B antibodies. His saliva contained A and H substances in normal amount of group AB secretor saliva and amount of B substance in his saliva was less than that found in group AB secretor saliva chosen at random. Sister of propositus was a group B variant and blood group pattern of her red cells, serum and saliva was identical with those of propositus.
