  Purpose

One of the goals of the Kansas City Diabetes Consortium is to identify and characterize genes and their products that are associated with T1DM. Characterization of such genes and their products can aid in developing new tools for risk assessment, development of new prevention strategies and monitoring progression of disease.

Study design: Descriptive, basic science pilot study. The results of this pilot study will be used to help design a much larger study to address the importance of viral response and autoimmune diabetes.

Biospecimen Retention:   Samples With DNA
Whole Blood saved frozen for 1 year

Estimated Enrollment: 64
Study Start Date: June 2006
Study Completion Date: April 2008
Detailed Description:

The hypothesis is that viral responsive genes are up-regulated prior to the onset of symptoms of Type 1 Diabetes (T1DM) and may correlate with increased expression of interferon alpha.

Both genetic and environmental factors contribute to risk of development of T1DM. There are a number of conflicting reports associating viral infections and T1DM in genetically susceptible individuals and causality has not been proven. Viruses may not have a large role in the initiation of islet cell autoimmunity but more of a role in acceleration of the disease leading to overt symptoms. There are no studies describing viral responsive gene expression in these individuals.
