Scoring titrations with anti‐Lu a on 81 members of the families of seven Lu(a+b—) propositi did not produce any evidence for the presence of Lu genes. In the Lu(a+b+) heterozygotes the Lu a antigen was only weakly expressed at birth ... the first 15 years. The red cells of Lu(a+b—) children gave scores comparable to those of adults. The reactions of Lu(a—b+) cord cells were somewhat weaker than those of adults but the red cells of Lu(a+b+) infants reacted very weakly with anti‐Lu a . Four infants born to mothers with anti‐ ...
