HLA-A, B and DR antigens in patients with gonadal dysgenesis.
HLA (human leukocyte antigens) antigens A, B, and DR were determined in a series of 50 patients with gonadal dysgenesis (GD), separated into different groups according to karyotype. There were no significant differences in frequency of HLA antigen types between GD patients and the population control. When frequencies of the HLA antigens in the various GD patient groups by karyotype were compared, only one significant difference was found: HLA-A3 was more common among GD patients with isochromosome X than among GD patients with karyotype 45,X (p < 0.001, corr. p < 0.008). Although GD patients have a higher expectancy for development of autoimmune disorders, and in our 50 patients thyroglobulin and/or microsomal antibodies were detected in 20 (i.e., 40%), we failed to find any increased frequency of specific HLA antigen types known to be associated with juvenile autoimmune thyroiditis.
