[HLA antigen and Willebrand's disease (author's transl)].

The frequency of HLA antigens was determined in 28 unrelated patients with Willebrand's disease and in 326 healthy controls. There was no significant difference between the two groups for any of the HLA antigens tested. Segregation analysis processed among the families of 26 of these patients didn't allow us to find any disorder of the HLA antigens distribution in the patient's group: transmission of the disease and transmission of the HLA haplotypes appear to be independant in 25 of 26 families studied. There is no linkage and no association between the Willebrand's disease genes and the HLA system genes.
