HLA-DQ and TAP2 genes in patients with insulin-dependent diabetes mellitus
Abstract:
We examined the prevalence of HLA-DRB1, DQB1, DQA1 and TAP2 genes in children with insulin-dependent diabetes mellitus (type 1 diabetes). These HLA and TAP2 alleles were identified by dot-blot analysis of polymerase chain reaction (PCR)-amplified genomic DNA with sequence-specific oligonucleotide probes. The results show that those DQB1 alleles, which carry non-aspartic acid at position 57, in conjunction with DQA1 alleles carrying arginine at position 52, are strongly associated with susceptibility to type 1 diabetes. The prevalence of the TAP2* 0201 allele in diabetic patients was significantly lower than that in normal controls. Analysis of the data suggests that DQ alleles have the primary association with type 1 diabetes and that the association of TAP2 alleles with the disease is secondary.

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
