Abstract The Human Leucocyte Antigen (HLA)-DMA and DMB genes are located in the HLA-D region between DQ and DP. HLA-DM molecules play an important role in the process of peptide loading to HLA class II antigens, both in regulating the dissociation of class II-associated invariant chain peptides (CLIP) and the subsequent binding of exogenous peptides to HLA class II molecules. In order to investigate the immunogenetic heterogeneity within the HLA-D region, we designed this study to explore the relationship between HLA-DMA, DMB, and genetic susceptibility to type 1 diabetes in Chinese. Our results showed that HLA-DMA*0103 and HLA-DMB*0103 alleles contributed to the predisposition, while HLA-DMA*0102 and HLA-DMB*0101 alleles conferred protection to type 1 diabetes in Chinese. HLA
