For example, the HLA-DRB1*14 supertype was found associated with MuSK MG, pemphigus and thrombotic thrombocytopenic purpura, HLA-DQB1*05 in Iglon5 parasomnia, thrombotic thrombocytopenic purpura and MuSK MG (15, 16, 18, 19, 89), HLA-DRB1*15 is associated with NF155 antibody positive CIDP, pemphigus and PLA2R antibody positive MN [in a Chinese population, up to 99% of patients with PLA2R antibodies carried either DRB1*15:01 or DRB3*02:02, and individuals with these alleles have a 99-fold increased risk of PLA2R-associated MN (43)]. The gene discussed is PMP22; the disease is pemphigus.
