Juvenile-onset diabetes HLA-A, -B, -C, and -DR alloantigens
H Solow, R Hidalgo and DP Singal
We studied the distribution of HLA-A, -B, and -C antigens in 94
juvenile-onset diabetic patients and of HLA-DR antigens in 62 of these
patients. The frequencies for HLA-B15, -B40, and -Cw3 were significantly
increased in the patient group as compared with the control group. With
respect to the B-cell specificities, DRw4 was significantly increased in
the patients. Analysis of the data to detect the possible presence of
primary and secondary associations between HLA alleles and diabetogenic
gene(s) indicated that DRw4 possessed a primary association with the
diabetogenic gene(s). As a result, B15, B40, and Cw3 possessed secondary
associations.
