Subjects with GD had a higher percentage of the genotype HLA-A*11:01-*11:01 (13.3% vs. 10.8%, P value = 3.15×10-4) and 02:07-11:01 (12.5% vs. 7.3%, P value = 1.83×10-17), HLA-B*40:01-*46:01 (12.5% vs. 8.3%, P value = 7.81×10-10) and *46:01-*46:01 (5.1% vs. 2.7%, P value = 4.73×10-9), and HLA-C*01:02-*01:02 (6.2% vs. 4.1%, P value = 8.67×10-7), *01:02-*03:04 (7.3% vs. 5.3%, P value = 2.80×10-5), and *01:02-*07:02 (12.6% vs. 8.8%, P value = 1.27×10-9) than the subjects without thyroid disorders (Table 2). The gene discussed is HLA-A; the disease is thyroid gland disorder.
