Type 1 diabetes is a disease of beta-cell destruction leading to insulin deficiency. Genes for type 1 diabetes have been identified; however, much of the genetic risk remains unexplained. Genetic variation within the apolipoprotein CIII (apoCIII) gene alters apoCIII levels, which are increased in type 1 diabetes and induce beta-cell apoptosis. We therefore hypothesize haplotypes within the apoCIII gene are associated with type 1 diabetes. DNA from 584 type 1 diabetic patients and 591 control subjects were genotyped for six single nucleotide polymorphisms (SNPs) in the apoCIII gene (C-641A, C-482T, T-455C, C1100T, C3175G, and T3206G). Two alleles of a haplotype block (promoter SNPs + C3175G) were associated with type 1 diabetes. The A-T-C-C allele frequency was higher in type 1 diabetes (0.19 vs. 0.16, P = 0.05), and the C-C-T-C allele was reduced in type 1 diabetes (0.60 vs. 0.65, P = 0.04). The odds ratio (OR) for A-T-C-C allele increased with 0, 1, and 2 copies (OR of 1.00, 1.24, and 1.60, respectively; P = 0.05) and decreased for the C-C-T-C allele (1.00, 0.97, and 0.73, respectively; P = 0.03). This haplotype block contains an insulin response element. Screening for this haplotype may identify at-risk individuals, and this pathway may offer a target for prevention of type 1 diabetes.
