Research Interests:

Type 1 diabetes (T1D) is an autoimmune disease that results in permanent destruction of the insulin producing beta cells of the pancreas, and a dependence on exogenous insulin for survival. T1D is a complex disease that involves both genetic and environmental risk factors. Until recently, the four accepted T1D genetic risk loci were: the HLA class II region (6p21), Insulin gene (11p15), CTLA4 gene (2q33), and the PTPN22 gene (1p13). Genome wide association studies (GWAS) have recently provided a new list of potential T1D predisposing genes, including the IFIH1 (Interferon Induced with helicase C domain 1) gene, also known as Melanoma differentiation associated gene 5 (MDA5). The protein encoded by this gene is a putative RNA helicase that has been implicated in innate immune defense against viruses. Evidence for involvement of IFIH1 in T1D etiology comes from a single nucleotide polymorphism (SNP) in the gene that is associated with T1D in case-control and family studies. We hypothesize that this association reflects a function for the IFIH1 gene in T1D susceptibility. We propose to test this hypothesis by comprehensively evaluating SNPs and haplotypes within the IFIH1 gene for association with T1D, and exploring possible functional roles for IFIH1 variants in relation to T1D.
