PG - 180-8 AB - The T-cell mediated autoimmune process that destroys pancreatic beta cells in type 1 diabetes (T1D) is a complex phenotype influenced by multiple genetic and environmental factors. Human leukocyte antigen (HLA) accounts for about half of the genetic susceptibility, through a large variety of protective and predisposing haplotypes. Other important loci associated with T1D, with much smaller effects than HLA, include the insulin variable number of tandem repeats, PTPN22, and CTLA-4. Detecting the association and confirming it beyond doubt is only the first step. Identifying the functional variant from among a block of polymorphisms in tight linkage disequilibrium and determining its biological consequences can be an even more challenging task. It is hoped that the identification of additional loci and functional analysis of known ones, no matter how small each individual effect is, will provide: (1) pathophysiological insights necessary for the development of preventive interventions; (2) risk prediction to identify individuals that can benefit from them, and (3) potentially, identification of distinct subgenotypes, with different immune dysregulation pathways leading to the common disease phenotype that may respond to different preventive interventions.
