HLA-DQA1 and type 1 diabetes mellitus: When we tested HLA alleles for association, in AFR and AMR ancestry the most significant association with risk was with HLA-DQA1*03:01 (ORAFR = 5.45, PAFR = 9.28 × 10−116; ORAMR = 2.91, PAMR = 2.44 × 10−21); while in EUR and FIN ancestry HLA-DQB1*03:02 was most strongly associated with type 1 diabetes risk (OREUR = 5.33, PEUR = 5.08 × 10−1145; ORFIN = 3.91, PFIN = 8.76 × 10−76).
