Transracial analysis is one method for distinguishing primary associations between insulin-dependent diabetes mellitus (IDDM) and HLA II alleles from those related to linkage disequilibrium. Black people have different DR-DQ relationships from other races and are a useful group to investigate HLA-D regions associated with IDDM. In this study, we compared the frequencies of HLA-DQA1 and DQB1 alleles in Senegalese IDDM and control subjects. DQA1*0301 was positively associated with insulin-dependent diabetes mellitus (p < 10(-9), OR 5.21), as were DQB1*0201 and *0302 (p < 10(-7) OR = 3.55, p < 10(-3) OR = 3.20, respectively). The positive associations with DQA1*0301, DQB1*0201 and DQB1*0302 are consistent with all racial groups investigated. However, taken together, the data in Senegalese population show that susceptibility and resistance to IDDM are associated both with particular haplotypes and DQA1-DQB1 heterodimers.

D003922 Diabetes Mellitus, Type 1 A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.
