Segregation of HLA-D Specificities with the HLA-B12 Allotype

In a search for bone marrow donors and HLA—D homozygous cells, MLC family studies were performed. Results of the experiments, in which the Seventh Workshop cells 7W569-KR and 7W568-WE were found, are presented here. Within the KR and the WE families two identified and two non-identified HLA—D alleles appear to be linked to the HLA—B12 allotype that both families carry.
