Moreover, using the human Type 1 Diabetes Genetics Consortium MHC dataset, we identified two single nucleotide polymorphisms within the β5i/LMP7-encoding gene sequences, which were in strong linkage disequilibrium, as independent genetic risk factors for type 1 diabetes development in humans.
To study the relationship of the large multifunctional proteasome 7 (LMP7) gene polymorphism with susceptibility to type 1 diabetes mellitus (DM-1) and the DR3 gene in south Chinese Han population.
A genomic polymorphism of LMP7 was found strongly associated with IDDM, and the Arg/His-60 polymorphism in LMP2 was found associated with IDDM only in subjects containing an HLA DR4-DQB1*0302 haplotype.
