| Research Abstract |
Most cases of type 1 diabetes mellitus are type 1A (T1A), caused by an autoimmune reaction, involving genetic and environmental factors, which ultimately disrupt insulin-producing pancreatic β cells.This study analyzed the HLA-DRB1, DQB1, DPB1, A, C, and B genes in Japanese patients with T1A to identify candidate genes specific for Japanese individuals. Some of the genes were also involved in diabetes in Caucasian. The results of TDT demonstrated no genomic imprinting of HLA genes in Japanese patients. We also identified SNPs in genes other than HLA.
