Similarly, no differences were seen when patients were divided according to the presence or absence of HLA-B*35, HLA-Cw*04, HLA-Cw*07, HLA-DRB1*301, HLA-DRB1*04, or HLA-DRB1*1101, alleles associated with thyroiditis (postpartum thyroiditis, Hashimoto disease), rheumatoid arthritis, Sicca syndrome, and diabetes,17 or HLA-DQB1*0301, previously correlated with recurrence in stage I and II melanoma patients. This evidence concerns the gene HLA-DRB1 and postpartum thyroiditis.
