Brief Summary

The overall objective of this study is to perform baseline and repeat assessments over time of the metabolic and immunologic status of individuals at risk for type 1 diabetes (T1D).
· To characterize their risk for developing T1D
· To describe the pathogenetic evolution of T1D and

Definition of T1D in the proband requires onset of diabetes before age 40 years and prescription of insulin therapy within one year of diagnosis.
