Abstract:
The rs763361 single nucleotide polymorphism (SNP) within the CD226 gene has recently been reported as a novel susceptible locus for type 1 diabetes. The CD226 gene is implicated in the regulation of a number of cells involved in immune mechanisms leading to beta-cell destruction in type 1 diabetes. The aim of the present study was to confirm the association of the CD226 gene with type 1 diabetes in Estonian population. The TT genotype [odds ratio (OR) = 2.29, 95% confidence interval (CI) = 1.25-4.18, P = 0.0071) and the T allele (OR = 1.48, 95% CI = 1.11-1.98, P = 0.0084) of the rs763361 SNP were associated with the risk of type 1 diabetes. The current study replicates the novel association of the rs763361 SNP in susceptibility of type 1 diabetes and supports the CD226 gene as a susceptible candidate locus for type 1 diabetes outside the major histocompatibility complex region.

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...
