Autoimmune polyendocrine syndrome type 2
（重定向自Schmidt syndrome）
Autoimmune polyendocrine syndrome type 2, a form of autoimmune polyendocrine syndrome also known as Schmidt's syndrome, or APS-II, is the most common form of the polyglandular failure syndromes. It is heterogeneous and has not been linked to one gene. Rather, patients are at a higher risk when they carry a particular human leukocyte antigen genotype (HLA-DQ2, HLA-DQ8 and HLA-DR4). APS-II affects women to a greater degree than men (75% of cases occur in women).
