title: HLA markers in parents of triploid conceptuses.
abstract: Twenty-eight HLA-A and B markers have been tested in 49 couples who had one or more triploid abortions. The antigen frequencies were compared to those of 209 couples and 591 normal individuals as controls. No significant deviations were observed. However, a non significant excess of antigens shared in common by both parents was shown in comparison with the normal couples. This could be related to a possible dispermy mechanism. On the other hand, a slight excess of A 28 may be in relation to a possible anomaly of gametogenesis.
